Default Error code

I have an P0106 error code come up after a diagnoistic check from onstar . I also had a reading done by a mechanic and I was told I need a sensor so my truck can stop cutting off and idling so horribly but I need the name of the sensor or something . If someone had this problem in the past please respond so my baby can be running smmothly again -trying to avoid the dealer .

Obviously, you DID NOT READ my post in the FAQ section requesting that members NOT post any old question that popped into their brain in that section. Maybe take a look at it?

Your code is thrown from the MAP sensor. It can mean the TPS snsor readings conflict with the MAP input, or it can mean you have a vacuum leak. Search for your code, there is tons of code reader input sites and info at large on the web. Here is an example:

These include P0105, P0106, P0107, P0108 & P0109, and can trip if the MAP sensor output remains too high or too low (out of range), or the MAP sensor readings do not correspond to the Throttle Position Sensor (TPS) readings.

MAP sensors monitor changes in intake vacuum, which is a way of determining engine load. When engine load goes up, intake vacuum drops. Vacuum is highest at idle and drops during acceleration and wide open throttle.

The computer uses the MAP sensor's input to vary ignition timing and the fuel mixture. So a MAP sensor problem may cause drivability problems such as surging, poor fuel economy and performance.

MAP sensors either generate a voltage or frequency signal as engine vacuum (load) changes. Vacuum leaks can cause problems with the sensor's reading, so check for leaks and the sensor's vacuum connection to the engine.

How to check: a MAP sensor's voltage or frequency output should change when engine vacuum (load) changes. If you don't see a change, the sensor is probably bad and should be replaced."

Good luck.
