Map sensor: Manifold Absolute Pressure sensor- it's a measure of manifold vacuum that is sent to engine computer; so it can figure out engine running conditions and how much gas to add for the correct air-fuel mixture.
You probably need a new sensor. I don't know what newmatic means? But, pneumatic is of or pertaining to air, so hey, you better diagnose this before buying a new map sensor- just check if your vacuum hoses are not deteriorated from age, check if you still have a good vacuum signal from the intake manifold. If you were to hook up a vacuum gauge to a intake manifold tap-like the one going to your map sensor-with the engine at normal idle, the gauge should show a nice steady needle somewhere between 16 and 22 inches on the dial face. It's a measure of inches of mercury if you understand science-most people don't so the dial face is very large and you just understand it as inches of vacuum-how much lower the air pressure is inside the intake, versus outside air pressure. All engines create manifold vacuum, and the best, newer engines have a very steady vacuum at idle of 21, or 22 inches on the gauge. That's what you look for, 16 and steady is okay, a good map sensor would be sending a good signal to the computer by a varied voltage signal: manifold pressure is known good, so to speak.

Now manifold pressure varies under different running conditions. But by looking at a vacuum gauge, you are confirming that your manifold vacuum is good, you have no vacuum leaks, no air or vacuum leaks anywhere that will upset the apple cart, and cause the computer to question the info from the map sensor.
If your vacuum reading is way below 16 inches, like 10 inches, or 12, or 14 and holding steady, well, don't you see, you have a major vacuum or air leak somewhere. Vacuum hoses, pcv hose, intake manifold gasket...somewhere, your engine is sucking in extra air, and it's causing havoc with the engine management controls. It's where a lot of poor running conditions occur. So, try a used or new map sensor, or buy a vacuum gauge for $20. It saves a lot of time looking for vacuum leaks, and it's also very good at detecting valve problems and other internal engine conditions. You just have to learn how to use it, and understand what it is telling you.
I think Dodge put the map sensor maybe on the firewall on the passenger side, not sure, it's been a lot of years ago.

SOURCE: dtc p0405 & p0406

The DTC P0405 is for (Exhaust Gas Recirculation Sensor Circuit "A" Low)

DTC P0406 is for (Exhaust Gas Recirculation Sensor Circuit "A" High)

This would indicate a problem with the EGR valve sensor, or the EGR valve itself is malfunctioning.

Just changed battery and MAPS on my 2010 Hyundai Santa Fe and check engine light is still on


Why did you change the MAP sensor? Was there a DTC code indicating problems? Do you still have the same code? Have you reset the codes (if that was the only code displayed)? Why did you change the battery?
If your check engine light is on, please provide the DTC code and a brief history of the problem and what you have done to resolve it.

How did engine idle too low?i come across dtc p0105 related to map sensor.engine check light display on mitsubishi pajero/gdi engine


I'm not sure I understand your question. When I first read it I thought you were saying you had an error code that the engine idle is low, but the error code you've given is for a MAP sensor problem which you mentioned in your post also. I'm going to guess that you've observed the low idle yourself, and when you ran the diagnostics the engine computer was complaining of a bad MAP sensor signal. This is triggered when the engine computer sees a change in another sensor that should correlate with a certain change in the MAP sensor, but the MAP sensor signal doesn't change as expected. Idle problems are a possible symptom of a bad MAP sensor, so this is not unreasonable. What your engine is telling you is that you should check the MAP sensor and its related wiring and hose connections to try to find your problem. If you fix the problem with the MAP sensor then your idle may start working properly again.

I have a 2000 Dodge Durango with 128,000 miles. The check engine light has been on and off the past few days. The OBD II code is P0108. What does this mean?


P0108 - MAP (Manifold Absolute Pressure/Barometric Pressure) Circuit High Input
The MAP (Manifold Absolute Pressure) sensor measures engine manifold negative air pressure. It's usually a three wire sensor: a ground wire, a 5 volt reference wire from the PCM (Powertrain Control Module) to the MAP sensor, and a signal wire that informs the PCM of the MAP sensor voltage reading as it changes. The higher the engine vacuum, the lower the voltage reading. The voltage should range between about 1 volt (at idle) to about 5 volts (WOT wide open throttle).

If the PCM sees the voltage reading from the MAP sensor is greater than 5 Volts, or if the voltage reading is higher than what the PCM considers normal under certain circumstances, a P0108 DTC will set.

Contact us if need additional details; good luck.

P0108 - (Manifold Absolute Pressure/Barometric Pressure Circuit High Input
The MAP (Manifold Absolute Pressure) sensor measures engine manifold negative air pressure. It's usually a three wire sensor: a ground wire, a 5 volt reference wire from the PCM (Powertrain Control Module) to the MAP sensor, and a signal wire that informs the PCM of the MAP sensor voltage reading as it changes. The higher the engine vacuum, the lower the voltage reading. The voltage should range between about 1 volt (at idle) to about 5 volts (WOT wide open throttle).

If the PCM sees the voltage reading from the MAP sensor is greater than 5 Volts, or if the voltage reading is higher than what the PCM considers normal under certain circumstances, a P0108 DTC will set.

Symptoms of a P0108 DTC code may include:
* MIL (Malfunction Indicator Lamp) will likely be on
* Engine may run poorly
* Engine may not run at all
* Fuel mileage may decrease
* Presence of black smoke at exhaust

Potential causes of a P0108 code:
* Bad MAP sensor
* Leak in vacuum supply line to MAP sensor
* Engine vacuum leak
* Short on signal wire to PCM
* Short on reference voltage wire from PCM
* Open in ground circuit to MAP
* Worn engine causing low vacuum

Possible Solutions:
A good way to diagnose if the MAP sensor is to blame would be to compare the KOEO (key on engine off) MAP sensor reading on a scan tool with the Barometric pressure reading. They should be the same because they both measure atmospheric pressure.

If the MAP reading is greater than 0.5 volt off of the BARO reading, then replacing the MAP sensor would likely fix the problem. Otherwise, start the engine and observe the MAP reading at idle. It should normally be about 1.5 volts (varies according to altitude).

a. If it is, the problem is likely intermittent. Check all the vacuum hoses for damage and replace as necessary. You can also try wiggle testing the harness and connector to reproduce the problem.
b. If the scan tool MAP reading is more than 4.5 volts, check the actual engine vacuum reading with the engine running. If it is less than 15 or 16 in. Hg, then the PCM is probably not seeing enough vacuum (due to a worn engine, perhaps) for a given operating condition (which causes a higher than normal voltage signal to the PCM) and setting the code. Repair the engine vacuum problem and retest.
c. But, if the actual engine vacuum reading is 16 in. Hg or more, then unplug the MAP sensor. The scan tool MAP reading should indicate that there is no voltage present. Check that the ground from the PCM is intact and also that the MAP sensor connector and terminals are tight. If the connection is good, then replace the map sensor.
d. However if, with KOEO, & the MAP sensor unplugged, the scan tool shows a voltage reading, then there may be a short in the harness to the MAP sensor. Turn the ignition off. At the PCM unplug connector and remove the MAP signal wire from the connector. Re-attach the PCM connector and see if with KOEO, the scan tool MAP reading shows voltage. If it still does, replace the PCM. If not, check for voltage on the signal wire you just removed from the PCM. If there is voltage on the signal wire, find the short in the harness and repair.


P0104 - Mass Air Flow (MAF) Circuit Intermittent
Basically this means that there is a problem with the Mass Air Flow High (MAF) sensor or circuit. A more technical description would be that the MAF is producing incorrect air flow readings. Other MAF sensor circuit DTC trouble codes are P0100, P0101, P0102, and P0103.

Symptoms: You will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness.

Causes: A code P0104 may mean that one or more of the following has happened:
* The mass air flow (MAF) circuit is incomplete (broken / frayed wire, etc.)
* There is an air leak in the intake system

Possible Solutions: The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
* Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
* Inspect for any air leaks near the MAF sensor.
* Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
* Replace the MAF sensor.



P0102 - Mass Air Flow (MAF) Circuit Low Input
Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. A more technical description would be that the MAF circuit had lower than expected voltage (air flow). Other MAF sensor circuit DTC trouble codes are P0100, P0101, P0103, and P0104.
Symptoms: You will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness.

Causes: A code P0102 may mean that one or more of the following has happened:
* The MAF may be disconnected, or a wiring connection may be bad
* The MAF may be dirty or otherwise contaminated (Note: if you use a reusable oiled air filter, be careful not to apply too much oil or that can contaminate the MAF).
* The MAF sensor may be faulty
* The vehicle computer may be faulty (very rare)

Possible Solutions: The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
* Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
* Inspect for any air leaks near the MAF sensor.
* Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.
* Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
* Replace the MAF sensor.




P0101 - Mass Air Flow (MAF) Circuit Range/Performance Problem
Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. The PCM detects that the actual MAF sensor frequency signal is not within a predetermined range of the calculated MAF value for more than 4.0 seconds. Other MAF sensor circuit DTC trouble codes are P0100, P0102, P0103, and P0104.

Symptoms: You will likely not notice any serious drivability problems, although there may be symptoms.

Possible Solutions: The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
* Inspect for the following conditions:
An incorrectly routed harness--Inspect the harness of the MAF sensor in order to verify that it is not routed too close to the following components:
- The secondary ignition wires or coils
- Any solenoids
- Any relays
- Any motors
* A low minimum air rate through the sensor bore may cause this DTC to set at idle or during deceleration. Inspect for any vacuum leaks downstream of the MAF sensor.
* A wide open throttle (WOT) acceleration from a stop should cause the MAF sensor g/s display on the scan tool to increase rapidly. This increase should be from 6-12 g/s at idle to 230 g/s or more at the time of the 1-2 shift. If the increase is not observed, inspect for a restriction in the induction system or the exhaust system.
* The barometric pressure (BARO) that is used in order to calculate the predicted MAF value is initially based on the MAP sensor at key ON.
* When the engine is running the MAP sensor value is continually updated near WOT. A skewed MAP sensor will cause the calculated MAF value to be inaccurate. The value shown for the MAP sensor display varies with the altitude. With the ignition ON and the engine OFF, 103 kPa is the approximate value near sea level. This value will decrease by approximately 3 kPa for every 305 meters (1,000 feet) of altitude.
* A high resistance on the ground circuit of the MAP sensor can cause this DTC to set.
* Any loss of vacuum to the MAP sensor can cause this DTC to set.

If you suspect the condition may be related to aftermarket accessories, refer to Checking Aftermarket Accessories in Wiring Systems. Here as an aid in resolving your P0101 trouble code (DTC)...

91 chevy 4.3 v-6 runs extremely rich when engine is cold gives codes 13, 33 and 54 I know what these codes are but I need to know is could the computer coolant temp sensor or the air cleaner temp sensor...


DTC - 13 Oxygen sensor circuit open or no activity
DTC - 33 MAP sensor circuit error (signal high indicating low vacuum)
DTC - 54 Fuel pump circuit low voltage

Start with checking the wire leads to the O2 sensors and MAP sensor. Look for any damages to the wire harness and replace any parts damaged or faulty.

The O2 and MAP sensor take reading and sends it to the ECM to recalibrate the fuel injector pulse to adjust the amount of fuel entering the cylinders. When there is an issue to the O2 sensor or MAP sensor and even both, the ECM will be set a a factory default to run rich to keep the engine running and at times the engine may not even run. Normal fuel to air ratio is 14.7:1 - 14.7 air to 1 parts fuel and at default it could be as high as 12.5:1. Good luck and keep me posted, be glad to help you get your truck running 100% again soon and please rate. replacing the thermostat and temperature sensor would also be a good thing since the 4.3 runs best at 190".
