94 Jeep Cherokee TPS - back feed


You are still getting high or low voltage at tps? What is the voltage and do you have a unstable idle? Put you + lead on terminal 3 and - lead on terminal 1 turn ignition on and check voltage to be at approximately 5 volts. You can also back probe with it connected at center wire and ground probe to a good ground at engine. Turn ignition on it should read between 0.20 - 0.90 slowly manually open throttle it should rise all the way to 4.5 voltd at full open. If its bad change tps if no 5.0 volts from pcm on first test check connections at pcm. The center tps connector supply wire comes from pin 22 and connection 3 ( which is 5 volt supply ) comes from pin 6. You should be able to back probe pin 6 turn ignition on and have 5 volts. If not 5 v brain has problem.

1996 jeep cherokeecranks no spark on coil or distributer


Test procedure:


1. Test powers and grounds at the Powertrain Control Module (PCM) on the C1 connector. Pins 2 and 22 are power, then check pins 31 and 32 for ground.

2. Next, test the 5 volt power supplies at pin 17 of the C1 connector and pin 31 of the C2 or middle connector for shorts to ground. Sensors on the circuit are the Camshaft Position (CMP) sensor, Crankshaft Position (CKP) sensor, Throttle Position Sensor (TPS), Manifold Absolute Pressure (MAP) sensor and Vehicle Speed Sensor (VSS).

3. Unplug the sensors on the 5 volt power supply, one at a time, while monitoring the 5 volt supply.

4. When the shorted sensor is unplugged, the PCM will wake up and scan tool communication will return.

5. The wiring harness could also be shorted to ground on one of the 5 volt power supply wires. Cut the wires at the PCM on pins C1-17 and just unplug the center connector. Then check for the 5 volts on the PCM of the connector or checking for any continuity to ground with the sensors unplugged at the PCM connector on C1-17 and C2-31 to check the wiring harness

The code was p0160 what does it mean.


This code is for a post-catalyst oxygen sensor that isn't operating properly or not at all. The catalyst, or catalytic converter is used to control emissions. This particular o2 sensor on Bank 2, position 2 is after the converter on bank 2 and monitors the catalyst efficiency of the catalytic converter on that bank. The P.C.M (Power train Control Module) compares the post-cat o2 sensor to the pre-cat o2 sensors to measure the cat's efficiency. The o2 sensor is a four wire sensor. The P.C.M supplies a reference voltage to the sensor of about half a volt and also supplies a sensor ground. 12 volts are supplied for the heater element and also a ground for the heater element (the heater in the sensor helps the sensor to warm up faster which allows the engine to reach closed loop sooner). The sensor varies the reference voltage the P.C.M gives it based on oxygen content of the exhaust. The change in oxygen content causes resistance changes in the sensor which affects the 0.5 volt reference voltage. Oxygen sensors are capable of varying the supplied voltage between 0.1 volts to 0.9 volts. Lean exhaust produces low voltage and causes the supplied 0.5 volts to drop. Rich exhaust produces high voltage and causes the supplied 0.5 voltage to increase. Pre-catalyst (front) o2 sensors switch between low and high voltage rapidly one or two times per second. However this sensor is a post-cat o2 sensor and may switch much slower & not vary as much (this is normal). If the sensor "sticks" or there are too few switches in a given time period, P0160 may set.

P0107 gm code


What does that mean?

The Manifold Absolute Pressure (MAP) sensor responds to changes in the intake manifold pressure (vacuum). 5 Volts is supplied to the sensor from the PCM (powertrain control module). Inside the MAP sensor is a resistor that moves in relation to manifold pressure. The resistor varies the voltage between about 1 volt to 4.5 volts (depending on engine load) and that voltage signal is returned to the PCM to indicate manifold pressure (vacuum). This signal is essential for the PCM to determine fuel delivery. A P0107 DTC is set when the PCM sees that the MAP signal voltage is less than .25 volts which is too low.
FB.init("dd7d9e9681341cde77587bc6a2029f6f"); OBD-Codes.com on Facebook Potential Symptoms

Anytime the MAP sensor signal is low the vehicle will likely have a very difficult time starting. Other symptoms may include:

  • Hard to start
  • Long cranking times
  • Sputtering/missing
  • Blowing black smoke
  • Poor fuel economy
  • Dies intermittently
  • MIL(Malfunction Indicator Lamp) illumination
Causes

The causes of a low MAP sensor signal circuit (P0107) could be any of the following:

  • Bad MAP sensor
  • Open or short in the signal circuit
  • Open or short in the 5 Volt reference circuit
  • Ground circuit open or shorted
  • Bad PCM

On my 2003 Dodge Neon SXT I need help with a couple of things. (1) I need someone to send me a diagram showing exactly where the coolant temperature sensor is and where the oil pressure sensor is. (2)...


2003 Dodge Neon (non-Turbo)

The coolant sensor threads into the rear of the cylinder head, next to the camshaft position sensor. New sensors have sealant applied to the threads.

The ECT Sensor is a Negative Thermal Coefficient (NTC), dual range Sensor. The resistance of the ECT Sensor changes as coolant temperature changes. This results in different input voltages to the PCM. The PCM also uses the ECT Sensor input to operate the low and high-speed radiator cooling fans.

11_21_2011_4_58_53_am.jpg

The combination coolant temperature sensor has two elements. One element supplies coolant temperature signal to the PCM. The other element supplies coolant temperature signal to the instrument panel gauge cluster. The PCM determines engine coolant temperature from the coolant temperature sensor.

As coolant temperature varies the coolant temperature sensors resistance changes resulting in a different input voltage to the PCM and the instrument panel gauge cluster. When the engine is cold, the PCM will provide slightly richer air-fuel mixtures and higher idle speeds until normal operating temperatures are reached.

The PCM has a dual temperature range program for better sensor accuracy at cold temperatures. At key-ON the PCM sends a regulated 5-volt signal through a 10,000-ohm resistor to the sensor. When the sensed voltage reaches approximately 1.25 volts the PCM turns on the transistor. The transistor connects a 1,000-ohm resistor in parallel with the 10,000-ohm resistor. With this drop in resistance the PCM recognizes an increase in voltage on the input circuit.

My mechanic told me my P0107 is possibly bad. Is this located in the same location as the P0108


P0107 - Manifold Absolute Pressure/Barometric Pressure Circuit Low Input

The Manifold Absolute Pressure (MAP) sensor responds to changes in the intake manifold pressure (vacuum). 5 Volts is supplied to the sensor from the PCM (powertrain control module). Inside the MAP sensor is a resistor that moves in relation to manifold pressure. The resistor varies the voltage between about 1 volt to 4.5 volts (depending on engine load) and that voltage signal is returned to the PCM to indicate manifold pressure (vacuum). This signal is essential for the PCM to determine fuel delivery. A P0107 DTC is set when the PCM sees that the MAP signal voltage is less than .25 volts which is too low.

Potential Symptoms: Anytime the MAP sensor signal is low the vehicle will likely have a very difficult time starting. Other symptoms may include:
* Hard to start
* Long cranking times
* Sputtering/missing
* Blowing black smoke
* Poor fuel economy
* Dies intermittently
* MIL(Malfunction Indicator Lamp) illumination

Causes: The causes of a low MAP sensor signal circuit (P0107) could be any of the following:
* Bad MAP sensor
* Open or short in the signal circuit
* Open or short in the 5 Volt reference circuit
* Ground circuit open or shorted
* Bad PCM

Possible Solutions: First, using a 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 reference circuit 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. (NOTE: On Chrysler products, a shorted Crank sensor, Vehicle speed sensor or any other sensor that utilizes the 5 Volt reference from the PCM can short out the 5 Volt reference. To fix simply unplug each sensor one at a time until the 5 Volt reference reappears. The last sensor unplugged is the shorted sensor.)

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.

MAP Sensor DTC's: P0105, P0106, P0107, P0108 and P0109.

Hope helps (remember rated and comment this).

No 8 volt supply from pcm


You likely already checked this but how about a broken timing belt. If the cams aren't turning the cam sensor isn't working and the pcm won't fire the plugs.
