Throttle Control Malfunction

DTC P2107

DTC Descriptors
DTC P2107
- Throttle Control Malfunction

Diagnostic Fault Information

Perform the Diagnostic System Check - Vehicle (Initial Inspection and Diagnostic Overview).

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 1 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, using a scan tool observe the DTC information 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

Perform the Diagnostic Repair Verification (Verification Tests).

Engine Control Module Replacement (Service and Repair) for engine control module replacement, setup and programming.
