P0108 code

This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. The sensor measures intake manifold vacuum, which varies depending on how wide open the throttle is. A map sensor measures barometric pressure.

This pressure is then converted into an electrical signal for the ECM.

This means that the voltage input to the ECU is too high and. TV - No long term contract. EricTheCarGuy - EricTheCarGuy- Stay Dirty ! Instead all the manuals say see MAF sensor.

The engine revs up high and back low about times before idling normally when first turned on. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself. Reading source code and extracting.

TDI and yesterday check engine light come on. The data is used to calculate air density and determine the engine’s air mass flow rate, which in turn determines the required fuel metering for optimum combustion. Make sure your spark plug boots are all. Just a few days ago I was driving down the interstate going about mph when my jeep jerked really bad and the check engi. Manifold Absolute Pressure Sensor High Voltage.

This code refers to the engine coolant temperature (ECT) sensor. The ECT is a thermistor (an electrical resistor whose resistance is greatly reduced by heating) and is located in a coolant passage in the cylinder head. How to test the map sensor gm 35l. Testing the osensors using the procedures below requires that the engine will idle normally and with reasonable stability.

If the code is current it will reappear. Press and release the odometer reset button to continue to the next module. Removed EGR valve, visual inspection OK Pintle closed. Check engine light on, and it. Blocked off valve, no extended crank no idle fluctuating.

You can usually look up the codes on obd-codes. I checked and cleaned my IAC, but I guess thats a possibility too? Does anyone have anymore info on theses codes. I popped the hood and before I got to the EGR assembly I noticed a problem with the electrical connector at the MAF sensor.

BAM, right back to where I started where it will not hold idle without throttling the accelerator. Cause: Engine running in closed loop, engine. Was giving it the business on the interstate last night and when i got home i shut the car off as I would normally do.

Sale of intangible assets like. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. Too low of a vacuum as seen by the PCM. The site for Ford truck owners, by Ford truck owners.

This is an all inclusive list intended to help you get not only a code definition, but also some information on what could cause these codes and what can be done to repair the related faults. I had the code checked and it. NEW PURPOSE CODES FOR REPORTING FOREX TRANSACTIONS RECEIPT PURPOSES Group No. With the engine idling, MAP value on a scan tool should read 3. In a vehicle, the mass airflow (MAF) sensor measures the amount of air going into the engine through the intake. Fault handling: (See section Fault handling III, other emission-related components and functions for more information.) - Type III.

A major vacuum leak can generate the trouble code. Diagnostic help Fault diagnosis concerns a fault in the sensor.

If all these codes came up after the timing chain was replace i would have to say that the timing is off a tooth or two. Topics in the Paccar MX-EPAEngine OBD Code Troubleshooting Manual. MAP sensor circuit problem. Based on some advice online I also replaced both oxygen sensors.

Erratic Idle Possible Causes. When diagnosing for this code , make sure you verify both the electric and mechanical cooling fans are not stuck at “On” position, as this will cause the engine to run at very low operating temperature. Got the KN with FIPK and got the code while towing 1000lbs in degree temps. It reset itself without any cleaning. I read somewhere else where a GM tech explained that is was the airflow increase beyond set parameters of the MAF and not the oil from the filter that was the cause.

I am looking for more help. Thermostat rationality) The Dealer replaced the thermostat and after drive cycles, it came on again for the same code. Water can leak into the connector from clogged sunroof drains, A-pillar leaks, or windshield or cowling leaks. I cleared the code and it came back a minute or so after starting and driving.

It says manifold pressure. Symptom before finding the code was check engine light lit and flashing 4LO light, truck would got into Limp mode Very scary when this first happene first couple of times this happened was able to reset computer by removing. MAP Sensor Circuit High Input.
