did you use new gm parts??

at this point, you need a scan tool to monitor the voltages of the sensor to see what is going on.

Diagnostic Aids

Inspect the TAC module connectors for signs of water intrusion. If water intrusion occurs, multiple DTCs may set without any circuit or component conditions found during diagnostic testing.

The APP sensor 1 and the Throttle Position (TP) sensor 1, 5-volt reference circuits are internally connected within the TAC module.

The APP sensor 2 and the TP sensor 2, 5-volt reference circuits are internally connected within the TAC module.

When the TAC module detects a condition within the TAC system more than 1 TAC system related DTC may set. This is due to the many redundant tests run continuously on this system. Locating and repairing 1 individual condition may correct more than 1 DTC. Remember this if you review the information stored in Captured Info.
