I from time to time trip a SES/MIL light and it's always for the same 2 codes.
P0106 - MAP range/performance
P0121 - TPS "A" circuit range/performance
I feel certain that they are related to the boost pressure in the intake as opposed to being in vacuum all of the time but wondered if anyone could verify that and tell me the fix. I know I can go in and kill those codes but I don't want to go turning things off for no reason.
It only seems to trip the light on long drives at highway speeds and if the light comes on it always shows both codes.
Can anyone shed some light on this?
