Conditions for Setting the DTC

P1516

The actual throttle position does not match the predicted throttle position for greater than 1 s.

P2101

The actual throttle position does not match the predicted throttle position for greater than 1 s.

P2119

The ECM detects that the throttle blade did not return to the default position when the TAC motor is de-energized for greater than 1 s.

P2176

The ECM detects that both throttle position (TP) sensors were greater than a predetermined voltage during the minimum throttle learn procedure for

greater than 2 s.

Action Taken When the DTC Sets

P1516, P2101, and P2176

* DTCs P1516, P2101, and P2176 are Type A DTCs.

* The control module commands the TAC system to operate in the Reduced Engine Power mode.

* A message center or an indicator displays Reduced Engine Power.

* Under certain conditions, the control module commands the engine OFF.

P2119

* DTC P2119 is a Type C DTC.

* The driver information center, if equipped, may display a message.

Conditions for Clearing the MIL/DTC

* DTCs P1516, P2101, and P2176 are Type A DTCs.

* DTC P2119 is a Type C DTC.

Diagnostic Aids

* If the Throttle Sweep Test is not available on the scan tool, observe the scan tool TAC Motor parameter while performing the following tests:
