To drive this point home a little further, I'll explain it like this: As you step on the accelerator pedal, The throttle plate opens and intake manifold vacuum decreases. This provides critical data needed for the Powertrain Control Module(PCM)to control the Air Fuel Ratio, the Ignition Spark Timing and many components of the Emission Control Systems. There needs to be a steady 5 volt reference voltage and a very good ground.

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. This voltage signal increases or decreases depending on the manifold vacuum that's created by the throttle angle. In other words... A qualified technician should then reset the OBD-II fault codes and road test the vehicle to see if the code comes back.

The MAP sensor high voltage output issue can cause excessive fuel consumption, rough operation, backfiring, difficulty starting in certain circumstances, and can cause other damage if continued to be driven. Code P0108 Jeep This could be due to MAP sensor failure or a mechanical problem with the engine. the fuel pump relay in my 850.Anyway, the soldering was repaired (remove all old solder and apply new, use lead/tin solder, not lead free).Since the old sealing was unusable, I applied

Rough idle. ‘Rotten egg’ smell coming from the exhaust. The code came back again a few days later, and I dropped a pan of wrenches on it trying to work on something else. Once the engine is running, the computer constantly monitors the changing voltage from the MAP to modify air fuel mixtures to match the load. Engine Code P0108 MAP sensor pin labeled with the number 3, in the image above, outputs this MAP signal to the PCM.

A fuel-injected engine may alternately use a Mass Air Flow (MAF) sensor to detect the intake airflow. Via the manifold absolute pressure (MAP) sensor. First, follow the procedure in the diagnosis to ensure there is the correct voltage to the sensor and from the sensor to the ECU. What are the symptoms of the P0108 code?
