DTC P2107: Throttle Control Malfunction
Diagnostic Fault Information
Perform the
Diagnostic System Check - Vehicle.
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
- 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. |
- 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
