C1155 pertains to a fault in the vehicle’s front wheel speed sensor circuit.

OBD code C1155 means Speed Wheel Sensor RF Input Circuit Failure.

This code is triggered by the ABS module when it detects a circuit malfunction in the right front wheel speed sensor.

The ABS module monitors the speed of each wheel using sensors to ensure proper operation of the ABS system and traction control.

When a fault is detected in the circuit of the right front wheel speed sensor, the C1155 trouble code is set.

Code C1155 indicates a fault in the front wheel speed sensor circuit.

OBDII code C1155 typically indicates a fault with the steering angle sensor.

To diagnose, use a scan tool to check for any related trouble codes and to monitor sensor data.

Visually inspect the wiring harness and connectors for any damage or corrosion.

Test the sensor’s power and ground using a voltmeter.

Ensure the sensor is properly calibrated and that there are no mechanical issues affecting its operation.

If necessary, recalibrate or replace the sensor.

Remember to clear the codes after any repairs are made.
