Details of the Dodge p0123 OBD Code

Dodge code P0123 relates to an issue with the throttle position sensor high input.

Dodge OBD code P0123 means that the Engine Control Module (ECM) has detected a high voltage signal from the Throttle Position Sensor (TPS).

The TPS is the component that triggers this fault code.

The TPS is responsible for monitoring the position of the throttle valve and sending this information to the ECM.

When the ECM receives a high voltage signal from the TPS, it triggers code P0123, indicating a potential issue with the TPS or its circuit.

Mechanic’s Tech Notes

For Dodge code P0123, check throttle position sensor circuit high voltage issues.

To diagnose and fix OBDII code P0123 on a Dodge, start by checking the throttle position sensor (TPS) circuit.

Use a voltmeter to test the TPS sensor’s voltage signal.

Ensure the sensor is receiving proper voltage and ground.

Inspect the wiring harness and connectors for any damage, corrosion, or loose connections.

Verify TPS data using a scan tool to see if it correlates with actual throttle position.

If necessary, recalibrate or replace the TPS sensor.

Additionally, check for any issues with the powertrain control module (PCM) that may be causing the fault code.
