I recently replaced the engine in this and it probably was a different year engine, but I used all of the sensors etc that were on the car. It as had a P0108 code from the start. I've changed the MAP sensor, plenum and made sure all of my grounds were good. I even did a voltage check on the sensor per this:Part 1 -Chrysler MAP Sensor Test (3 Wire Sensor) P0107, P0108. and the sensor is good. Also, it starts hesitating at 3800 RPMs, whether driving or sitting still. Idles fine, runs smooth up to 3800. ANy ideas?

 

P0108 is MAP sensor voltage is too high. The MAP sensor voltage should not exceed 4.96 volts. If it's shorted to either battery voltage or 5.0 signal voltage, there's your problem. Could be the result of a wiring problem or an internal computer problem.

 

Finally got it figuered out. All of my voltages seemed correct, so I figured the signal was not getting to the ECM. I rewired the plug and Viola! it worked fine. Thanx for the help
