Details of the Dodge p1755 OBD Code

Dodge fault code P1755 relates to the transmission throttle valve position sensor circuit.

Dodge OBD code P1755 indicates a transmission throttle valve position sensor circuit malfunction.

This code is triggered by the Powertrain Control Module (PCM) when it detects an electrical issue in the transmission throttle valve position sensor circuit.

The sensor is responsible for monitoring the position of the throttle valve in the transmission.

When a fault is detected in this circuit, the PCM illuminates the Check Engine Light and stores the P1755 trouble code.

This issue can lead to drivability problems and should be addressed promptly to prevent further damage to the transmission system.

Mechanic’s Tech Notes

For Dodge code P1755, check for issues with the transmission governor pressure sensor circuit.

To diagnose and fix OBDII code P1755 on a Dodge, start by checking the Transmission Control Module (TCM) power and ground using a multimeter.

Verify TCM communication over the Controller Area Network (CAN) using a scan tool.

If the TCM does not respond, reprogramming or reflashing may be necessary.

Additionally, visually inspect the wiring harness and connectors for any damage, and ensure connector pins are not broken, bent, pushed out, or corroded.

This thorough inspection can help identify and resolve the issue causing the P1755 fault code.
