p121 code
Got a p121 code that will come on for a little while than turn off. The throttle body position sensor or something. Anybody know what the deal with that is?

The tuner needs to fix the criteria for this test. It has to do with the P0101, P0106, P0121 test.

Bad connection will cause or faulty tune trying to force throttle body beyond operaring limits

Conditions for setting DTC
DTC P0121 The TP sensor 1 disagrees more than 9% from TP sensor 2 or TP sensor 1 disagrees more than 9% from the predicted value. Either condition exists for more than 4 seconds. Try increasing the values of C0807/8
