DTC Descriptors
DTC P2107 Throttle Actuator Control (TAC) Module Internal Circuit

Circuit/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 vehicle speed is 0 km/h (0 mph).
^ The engine speed is less than 40 RPM.
^ The engine coolant temperature (ECT) is 5-85° C (41-185° F).
^ The intake air temperature (IAT) is 5-60° C (41-140° F).
^ The ignition voltage is more than 10 volts.
^ The accelerator pedal position (APP) is less than 15 percent.
^ 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 C DTC.

Conditions for Clearing the DTC
DTC P2107 is a Type C DTC.

Circuit/System Verification
1. Ignition ON, observe the DTC information with a scan tool for 30 seconds. DTC P2107 should not set.
^ If DTC P2107 sets, replace the ECM.

2. 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.

Repair Instructions
