The throttle actuator control (TAC) monitors the throttle position. The throttle blade is spring loaded in both directions, and at rest is slightly open. When the throttle blade is not driven in either direction, it returns to this position. If the TAC module determines that the throttle blade has not returned to the correct de-energized position, the TAC module sends a message to the powertrain control module (PCM) across serial data, and DTC P2110 sets.
• | The ignition is in the Run position with the engine OFF. |
• | DTC U0107 is not set. |
• | The system voltage is more than 8.5 volts. |
• | The system is not in Battery Saver mode. |
• | The DTC runs continuously when the above conditions are met. |
The TAC module detects the throttle blade has not returned to the correct de-energized position.
• | DTC P2119 is a Type A DTC. |
• | The control module commands the TAC system to operate in Reduced Engine Power mode. |
DTC P2119 is a Type A DTC.

Remove the throttle body assembly. The throttle blade should move without obstructions.
⇒ | If an obstruction is found, repair as necessary. |
⇒ | If no obstruction if found or the condition can not be repaired, replace the throttle body assembly. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
