Details of the Chrysler p2101 OBD Code
Chrysler code P2101 relates to an issue with the throttle actuator control motor circuit.
Chrysler OBD code P2101 indicates a problem with the throttle actuator control motor circuit.
This code is triggered by the Engine Control Module (ECM) when it detects that the actual throttle position does not match the desired throttle position.
The throttle actuator control motor is the component that triggers this fault code.
It is responsible for controlling the opening and closing of the throttle plate based on driver input and other factors such as engine load and speed.
The signal or system involved in this fault code is the throttle actuator control circuit.
This circuit includes the throttle actuator control motor, throttle position sensor, wiring, and connectors.
When there is a discrepancy between the actual and desired throttle positions, the ECM sets code P2101 and illuminates the Check Engine Light to alert the driver of the issue.
Mechanic’s Tech Notes
For Chrysler code P2101, throttle actuator control motor circuit range/performance issue may be present.
To diagnose and fix OBDII code P2101 in a Chrysler vehicle, start by checking the throttle actuator control motor circuit.
Use a voltmeter to test for proper voltage at the throttle actuator motor connector.
Ensure the wiring harness and connectors are in good condition, looking for any damage or corrosion.
Verify the throttle actuator’s operation using a scan tool to see if it responds correctly.
If necessary, reflash the powertrain control module (PCM) to address any software issues.
Additionally, inspect the throttle body for any carbon buildup that may be affecting its operation.
