DTC Descriptor
DTC P2107: Throttle Actuator Control (TAC) Module Internal CircuitCircuit/System Description
The engine control module (ECM) controls the throttle valve by applying a varying voltage to the throttle actuator control motor. The ECM monitors the actual throttle valve position using throttle position (TP) sensor 1 and 2. The ECM amplifies the TP sensor 1 signal in order to obtain a more accurate signal. The ECM monitors the TP sensor 1 amplification output whenever the ignition is ON and a closed throttle test is performed.
Conditions for Running the DTC
| • | The ECM is performing the closed throttle test with the ignition ON and the engine OFF. |
| • | DTC P2107 runs once the above conditions are met during the throttle actuator control system initialization. |
Conditions for Setting the DTC
The ECM detects the internal TP sensor 1 amplification output does not correlate with the TP sensor 1 signal voltage for more than 4 seconds.
Action Taken When the DTC Sets
DTC P2107 is a Type A DTC.
Conditions for Clearing the DTC
DTC P2107 is a Type A DTC.
Circuit/System Verification
- Ignition ON, observe the scan tool DTC information parameter for 30 seconds. DTC P2107 should not set.
- If the vehicle passes the Circuit/System Verification test, then operate the vehicle within the conditions for running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records List.
| ⇒ | If DTC P2107 sets, replace the ECM. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
