* DTC P2119 runs continuously when the above conditions are met.
P2176
* DTCs P0120, P0121, P0122, P0123, P0220, P0222, P0223, or P1682 is not set.
* The ignition is ON.
* The run/crank or powertrain relay voltage is greater than 6 V and reduced power is not active.

Conditions for Setting the DTC
P1516
The actual throttle position does not match the predicted throttle position for greater than 0.2 s.
P2101
The actual throttle position does not match the predicted throttle position for greater than 0.2 s.
P2119
The ECM detects that the throttle blade did not return to the default position when the TAC motor is not powered-up, during power down for
greater than 0.5 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:
- Slowly depress the accelerator pedal to WOT and then slowly return the pedal to closed throttle. Repeat the procedure several times.
- Rapidly depress the accelerator pedal from the rest position to the wide open throttle position (WOT) and release pedal. Repeat the
procedure several times.
