The coil needs battery voltage ( 12+ ) to function.
A faulty map sensor would not affect the ignition system unless it shorted out the computer.
Code 700 is for a problem with the transmission module.
Code 562 is for the charging system being below 11 volts.
Code 113 is for a problem with the intake air temp sensor circuit.

SOURCE: Transmission Problems

code P0700 means that there is a code in the trans controller. P0605 means there is an internal failure in the trans controller that can not be repaired. The only step in checking this code is replacing the trans controller. The controller is not the solenoid pack . Its the actual transmission computer.

SOURCE: check engine light is on 3 codes p0740,p0601,&

P0700 - Transaxle Control System Fault Conditions
The P0700 code is for information only and the next step is to check for transaxle codes in the Transaxle Control Module (TCM). So you'll have to have the dealer or another qualified shop/technician pull the transaxle codes from the TCM and go from there.

P0740 - Torque Converter Clutch Circuit Malfunction

P0601 - Internal Control Module Memory Check Sum Error
What does that mean?
Basically that means that there is an interal fault in the Powertrain Control Module (PCM). There have been many reported PCM failures on Chrysler/Dodge products although it is possible for this to happen on any vehicle. In Dodge/Chrysler products, a P0601 trouble code means that a serial communication failed inside the computer at least 6 times.

Symptoms
Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light. Typically the engine runs fine, gauges work, etc.

Causes
A code P0601 in most cases means the PCM has gone bad. This is possibly due to a short-circuit inside the PCM. Or, if you disconnect the wires/connector from the PCM while the battery is still connected, that may also cause this code.

Possible Solutions
With a P0601 OBD-II trouble code, the most common fix is to replace and reprogram the PCM. In a few cases the dealer may be able to reflash the PCM and get it working. But more than likely the PCM will need to be replaced and reprogrammed (we recommend you take it to a dealership for this). The good news is it *may* be covered under your emmissions warranty. So even if you're out of bumper-to-bumper warranty or powertrain warranty, check your warranty guide or dealer to see if this is covered.

Other people have reported that they cleared the code only for it to return again and again. Keep in mind that most shops can replace the PCM but not all can program it.


Good luck!

My 1993 dodge shadow died and wouldn't start back it turns over but won't spark. When I turn the key I get the code 355 or 13 What does this mean


Check the codes again- there are only 2-digit codes. Code 13 is saying "MAP sensor is not detecting any change during self-test". It could be a bad MAP sensor (Manifold Absolute Pressure-the vacuum sensor for the engine), but sometimes it can be a wire harness problem. If a new or known-good Map sensor doesn't fix it, you will need a mechanic to check the MAP sensor circuit.


Usually when an engine dies and won't restart, it is a gas or spark problem. Listen for the fuel pump to turn on with key in on, not start-it should turn on for about 2 seconds to put pressure in the fuel line and up to the engine. If the pump is working, next check for spark at a spark plug wire, with the engine being cranked over. If you have a blue, snapping spark, the ignition is probably good. If no spark, it could be a bad ignition coil, a bad Ignition Control Module, or possibly a bad Crankshaft Position Sensor.

OPERATION

See Figures 1, 2 and 3

0900c1528003c4db.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 3: MAP sensor location-3.3L and 3.8L engines
The PCM supplies 5 volts of direct current to the Manifold Absolute Pressure (MAP) sensor. The MAP sensor then converts the intake manifold pressure into voltage. The PCM monitors the MAP sensor output voltage. As vacuum increases, the MAP sensor voltage decreases proportionately. Also, as vacuum decreases, the MAP sensor voltage increases proportionally.
With the ignition key ON , before the engine is started, the PCM determines atmospheric air pressure from the MAP sensor voltage. While the engine operates, the PCM figures out intake manifold pressure from the MAP sensor voltage. Based on the MAP sensor voltage and inputs from other sensors, the PCM adjusts spark advance and the air/fuel ratio. The MAP sensor is mounted to the intake manifold, near the throttle body inlet to the manifold. The sensor connects electrically to the PCM.


TESTING

See Figures 4, 5, 6 and 7

Fig. Fig. 4: Disengage the MAP sensor connector-3.0L engine shown

WARNING When testing the MAP sensor, make sure the harness wires do not become damaged by the test meter probes.

  1. Visually check the connector, making sure it is attached properly and that all of the terminals are straight, tight and free of corrosion.

Fig. Fig. 7: Using a digital volt-ohmmeter, test the MAP sensor voltage-3.0L engine shown

  1. Test the MAP sensor output voltage at the sensor connector between terminals B and C (2.4L, 3.3L and 3.8L engines), or A nd B (3.0L engine).
  2. With the ignition switch ON and the engine not running, the output voltage should be 4-5 volts. The voltage should fall to 1.5-2.1 volts with a hot, neutral idle speed condition. If OK, go to the next step. If not OK, go to Step 5.
  3. Test the PCM terminal 36 for the same voltage described in the previous step to make sure the wire harness is OK. Repair as necessary.
  4. Test the MAP sensor ground circuit at the sensor connector terminal A (2.4L, 3.3L and 3.8L engines) or C (3.0L engine) and PCM terminal 43. If OK, go to the next step. If not OK, repair as necessary.
  5. Test the MAP sensor supply voltage between the sensor connector terminals A and B (2.4L, 3.3L and 3.8L engines) r A and C (3.0L engine) with the ignition key in the ON position. The voltage should be about 4.5-5.5 volts.
  6. There should also be 4.5-5.5 volts at terminal 61 of the PCM. If OK, replace the MAP sensor.
  7. If not, repair or replace the wire harness as required.


REMOVAL & INSTALLATION

See Figures 1, 2, 3 and 4
The MAP sensor is mounted on the intake manifold near the throttle body inlet to the manifold.

  1. Disconnect the negative battery cable.
  2. On the 3.0L engine only, disconnect the vacuum hose from the MAP sensor.
  3. Detach the electrical connector from the MAP sensor.
  4. Unfasten the mounting screws, then remove the MAP sensor from the vehicle.

To install:
  1. Install the sensor onto the intake manifold and tighten the mounting screws to 35 inch lbs. (4 Nm).
  2. Attach the sensor electrical connector.
  3. On the 3.0L engine, connect the vacuum hose to the MAP sensor.
  4. Connect the negative battery cable.

Ran an ecu fault code reader on my focus and it shows up beromatric low presure what is this ?


Hi there,

If you are correct with your code reader, this condition should trigger fault code: P0107.

This relates to your MAP/BARO Sensor's signal voltage is too low (below 0.25v).

This condition will cause all sorts of engine running issues....

First, using your scan tool with the Key on and engine running, monitor the MAP Sensor voltage. If it is reading less than 5 volts, turn engine off, unplug the MAP sensor and, using a DVOM (Digital Volt/Ohm Meter) check for 5Volts on the 5 Volt reference circuit.


1. If there is not 5 Volts on the reference circuit, then check for the reference voltage at the PCM connector. If it is present at the PCM connector but not the MAP connector, repair the open in the wiring loom between the PCM and MAP harness connector.


If 5 Volt reference is NOT present at the PCM connector, check powers and grounds of PCM and repair/replace as needed.


2. If you have a 5 Volt reference at the MAP connector, jumper the 5 volt reference circuit to the signal circuit. Now check the MAP voltage on the scan tool. It should be 4.5 to 5 Volts. If it is, replace MAP sensor. If not, repair open/short in the signal circuit wiring and re-check.


3. If all appears okay, perform a wiggle test. Start engine and manipulate the harness, connector and tap on the MAP sensor. Note any changes in voltage or engine speed. Repair connector, harness, or sensor as needed.


4. If the wiggle test checks out, use a vacuum pump (or just use your lungs) to draw a vacuum on the MAP sensor vacuum port. As you add vacuum the voltage should decrease. With no vacuum, the MAP sensor should read approximately 4.5 volts. If there is no change in MAP sensor reading on the scan tool, replace MAP sensor.

I would check the fuel pressure regulator for a torn diaphragm. If that was good, I would test the MAP sensor. The regulator is usually on the fuel rail on top of the engine, depending on which engine you have. Pull the vacuum hose off the regulator and plug the hose with a golf tee. Start the engine and check to see if gas spits out of the vacuum port on the regulator. If any gas comes out, replace the regulator. If you don't see anything on the fuel rail with a vacuum hose attached, you may not have a separate regulator. In that case, go on to the MAP sensor test.

More likely the MAP sensor. A new sensor is $65, so I recommend you test it to see if it's bad. Test procedures are pasted below. Please let me know if it passes the tests or if you have any questions, and thanks for using FixYa.

OPERATIONThe PCM supplies 5 volts to the Manifold Absolute Pressure (MAP) sensor. The MAP sensor converts what it reads as the amount of intake manifold pressure into a return signal. The PCM monitors the MAP sensor output voltage. As vacuum increases in the intake manifold, the MAP sensor voltage decreases proportionately. Also, as vacuum decreases, the MAP sensor voltage increases proportionately.
During engine cranking, before the engine starts running, the PCM determines atmospheric air pressure from the MAP sensor voltage. While the engine operates, the PCM determines the intake manifold pressure from the MAP sensor voltage.
Based on MAP sensor voltage and inputs from other sensors, the PCM adjusts spark advance and the air/fuel mixture.

Fig. Fig. 2: Manifold absolute pressure (MAP) sensor connector terminal pin locations-1993-95 models


Before testing any electrical component, inspect the wiring and connectors for damage. Also wiggle the connectors to ensure a that they are firmly engaged. When testing the sensor, use a high input impedance digital volt-ohmmeter. Insert the tester leads through the back of the connector. Do not disconnect the electrical harness.

  1. Inspect the vacuum hose connections at the sensor and throttle body. Repair or replace the hoses, if any hoses are cracking or vacuum is leaking.

For the following step, do not unplug the sensor connector-it must stay plugged in.
  1. Make sure that the sensor wiring connector is fully inserted into the sensor (loose connections can create trouble codes). Check the MAP sensor output voltage by inserting the negative lead of a voltmeter into the back of terminal 2 and the positive test leads through the back of the harness connector terminal 3 (as marked on the sensor body). Refer to the accompanying wiring illustration. With the ignition switch in the ON position and the engine OFF , the output voltage should be 4-5 volts.
  2. Start the engine and allow to idle at normal operating temperature. The output voltage should drop to 1.5-2.1 volts.
  3. Test the PCM terminal 36 (1993-95 models), and terminal 1 (1996-97 models) for the same voltage described above to verify the wire harness condition. Repair the wiring harness if the voltage is not the same.
  4. Test the MAP sensor supply voltage at the sensor connection terminal 2 and 1 with the ignition ON . The voltage should be 5 volts. Check the supply voltage at terminal 61 of the PCM. This should also be 5 volts.
  5. Using an ohmmeter, test the MAP sensor ground circuit at the sensor connection terminal 1 and at the PCM terminal 43 (1993-95 models), terminal 4 (1996-97 models). Repair the wire harness for an open circuit if infinite resistance is detected.

I have this eobd code problem p0105 in my elantra, where those sensors?


P0105 - Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction
The MAP (Manifold Absolute Pressure) sensor is part of the fuel management system. It reacts to changes in engine manifold pressure. The PCM (Powertrain Control Module) monitors the MAP sensor continually to properly run the engine. Changes in engine load require changes in the amount of fuel injected, and timing of the ignition system, etc. An engine under load has more manifold pressure(or less vacuum) than an engine that is coasting. As the load changes, the MAP sensor voltage signal to the PCM changes accordingly. To check the MAP sensor operation, though, the PCM watches other sensors to verify that the MAP sensor is working properly.

For example, the PCM compares the TPS (Throttle Position Sensor) signal to the MAP signal to verify the MAP signal isn't "sticking". If the PCM doesn't see a MAP sensor change immediately follow a change in the throttle pedal sensor, it knows there is a problem with the MAP sensor and sets P0105. Or, if the PCM notices that the TPS indicates the engine is under load, but the MAP signal indicates that the engine is "coasting" it, again, knows there is a problem with the MAP sensor or TPS and sets P0105.

Symptoms of a P0105 check engine light code may include:
* Poor running engine
* Engine runs rich
* Engine won't idle
* Engine backfires through tailpipe
* Engine misfire under load or at idle
* MIL (Malfunction Indicator Lamp) illumination
* In some extreme cases there may be no symptoms other than MIL illumination

Causes: A P0105 DTC could be caused by:
* MAP sensor vacuum hose disconnected or plugged
* Bad MAP sensor
* Bad TPS
* Damaged or problematic MAP sensor connector
* Damaged or problematic TPS connector
* Damaged wiring
* Short to reference voltage on signal circuit of MAP sensor
* Loss of ground to MAP sensor or TPS
* Open on signal circuit of MAP sensor
* Bad PCM

Possible Solutions:
Using a scanner or code reader, turn the ignition on and engine OFF; what does the MAP sensor voltage read? It should be about 4 Volts for sea level. If you are at a higher altitude, it should decrease about half a volt or so for each 1,000 ft. of altitude (this will vary from model to model) Or if you have a separate MAF (Mass air flow) sensor on your vehicle, they are usually equipped with a Barometric pressure reading. If so, the Baro reading should match the MAP reading (they both measure ambient air pressure). If they're roughly equal, then, check for Freeze Frame data of the MAP sensor (if available).

NOTE: Freeze Frame data is the PCM recording a fault when it happens. It captures the readings of the various PIDS (parameter identifiers)available to troubleshoot what happened. It's like a recording of the problem as it happened. At idle a typical MAP sensor Voltage reading should be about a volt, and at WOT (wide open throttle) it should approach 4.5 to 5 Volts. As for the TPS, at idle, the voltage reading is about 1 Volt or less. As the throttle is opened the reading will increase to 4.5 Volts at WOT. Do the two readings make sense? For example, if the TPS reading on Freeze Frame data shows 2.5 Volts (indicating partial throttle) does the MAP sensor indicate a reading that isn't at either extreme? Using the Freeze Frame data (if available) compare the MAP reading to the TPS when the problem occurred. This can help you identify what happened

If you have no access to Freeze Frame data then check if the MAP sensor voltage changes when you apply vacuum to it. You can do this by mouth or a vacuum pump. The voltage should increase as you apply vacuum. If the reading doesn't change as you apply vacuum, make sure there are no obstructions in the hose to the sensor. If the hose is clear, the MAP sensor is usually bad, but it doesn't rule out the following from causing the problem: Does the MAP sensor appear to be stuck at less than .5 Volts? Then:

NOTE: This code shouldn't set if the MAP is stuck at extremely low voltage, however, I'm adding it in because there's no way to know for certain for which vehicles a low voltage condition may set a P0105.

1. Inspect the wiring harness and MAP sensor connector. Repair any damage
2. Unplug the MAP sensor connector. Also, at the PCM connector, remove the MAP sensor signal wire and check for continuity to the MAP sensor connector. If there is infinite resistance, then repair open in MAP signal circuit. If the signal wire has continuity to the MAP sensor connector, then check for 5 volt reference voltage to the connector and a good ground. If both are present, then re-install all removed wiring and replace the MAP sensor.

Does the MAP sensor appear to be stuck at full 4.5 voltage? Then:
1. Inspect the wiring harness for damage. Repair as needed
2. Remove the MAP sensor signal wire from the PCM connector. With a voltmeter measure the voltage with KEY ON ENGINE OFF. Is there 4.5 Volts? If so, unplug the MAP sensor and recheck. If it is still present, then repair short between the signal wire and 5 volt reference wire.
3. If unplugging the MAP sensor causes the voltage to disappear, check that the ground is intact. If it is, then replace the MAP sensor due to internal short.

MAP sensor codes include P0106, P0107, P0108 and P0109 .


LOCATIONS:
Manifold Absolute Pressure (MAP) Sensor: The MAP sensor is located against the firewall to the left side of the engine.
Barometric Pressure Sensor: This sensor is installed on the VAF sensor; Volume Air Flow Sensor Is located in the air intake plenum assembly.

Hope this helps.

1999 olds 88. I have replaced the fuel pump, sending unit, filter, mass air flow senson, spark plugs and wires, fuel pressure regulator. The car idles fine but when you apply pressure to the gas pedal it...


recommend you check your MAP sensor. You will need a voltmeter.
If you don't have a vacuum gage, just use your mouth to pull a vacuum on the hose and see if the voltage drops when you do.
Let me know if you have questions.


OPERATION The Manifold Absolute Pressure (MAP) sensor, used on 1996-99 vehicles, measures the changes in intake manifold pressure which result from engine load/speed changes, and converts this information to a voltage output. The MAP sensor reading is the opposite of a vacuum gauge reading: when manifold pressure is high, MAP sensor value is high and vacuum is low. A MAP sensor will produce a low output on engine coast-down with a closed throttle while a wide open throttle will produce a high output. The high output is produced because the pressure inside the manifold is the same as outside the manifold, so 100 percent of the outside air pressure is measured.
The MAP sensor is also used to measure barometric pressure under certain conditions, which allows the PCM to automatically adjust for different altitudes.
The MAP sensor changes the 5 volt signal supplied by the PCM, which reads the change and uses the information to control fuel delivery and ignition timing.


TESTING See Figures 1 and 2

  1. Visually check the connector, making sure it is properly connected and that all of its terminals are straight, tight and free of corrosion.
  2. With the ignition ON , check the voltage between terminals A and B (probe the back of the connector to connect to these wires). It should be above 4 volts. Apply 15 in. Hg of vacuum at the MAP vacuum port and check the voltage again. The voltage should be 2 volts now.

When pumping up and releasing the vacuum, check to make sure the voltage readings are smooth. When applying vacuum to the sensor, the change in voltage should happen instantly. A slow change in voltage could point to a faulty sensor.

Fig. Fig. 2: MAP sensor voltage specifications

  1. If the sensor voltage is not within specification, check for a 5 volt reference at terminal C. If the reference signal is found, the sensor is faulty.
  2. If the sensor and circuits are functional, the PCM may be faulty.


REMOVAL & INSTALLATION

3.8L (VIN K) Engine
See Figure 4
On these engines, the MAP sensor is mounted to the PCV valve cover.

  1. Disconnect the negative battery cable.
  2. Detach the MAP sensor electrical connector.
  3. Carefully bend the locking tabs holding the MAP sensor to the PCV valve cover, just enough to remove the MAP sensor.
  4. Pull the MAP sensor straight out of the PCV valve cover.

I have a 2002 TrailBlazer with the straight 6,diognostic check said #3 cylinder was dead or misfiring, also map sensor showed up. #3 cylinder was misfiring, so to test the coil pack I swapped #3 coil pack...


did you replace only one spark plug? that can cause issues because of differences in resistances between cylinders. also, did the map code stay off after replacing
?
