(TAC) motor. The ECM monitors the duty cycle that is required to actuate the throttle valve. The ECM monitors the throttle position (TP) sensors 1
and 2 to determine the actual throttle valve position.
Conditions for Running the DTC
P1516 and P2101
* DTC P0606 and P1682 is not set.
* The run/crank or powertrain relay voltage is greater than 6 V and reduced power is not active.
* The engine is running or the following conditions are met:
- The engine is not running.
- The ignition voltage is greater than 11 V.
- The TAC system is not in the Battery Saver mode.
- The ECM is commanding the throttle.
- The ECM has learned the minimum throttle position.
* DTC P1516 and P2101 run continuously when the above conditions are met.
P2119
* DTCs P0120, P0122, P0123, P0220, P0222, P0223 are not set.
* The ignition is ON.
* The run/crank or powertrain relay voltage is greater than 6 V and reduced power is not active.
* The ECM is not commanding the throttle blade.
* 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.
* The ECM enable the minimum throttle learn procedure.
* DTC P2176 run continuously when the above conditions are met.
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.
