Details of the c123f OBD Code
Code C123F relates to an issue with the wheel speed sensor circuit.
OBD code C123F means a steering angle sensor circuit range/performance issue.
This code is triggered by the Electronic Stability Control (ESC) module when it detects that the steering angle sensor signal is out of the expected range or not performing within specified parameters.
The steering angle sensor is a critical component of the ESC system, providing data on the steering wheel angle to help the system determine the vehicle’s intended direction.
Mechanic’s Tech Notes
Code C123F indicates an issue with the wheel speed sensor on the left front wheel.
OBDII code C123F typically indicates a problem with the Transmission Control Module (TCM).
To diagnose this, check TCM power and ground using a multimeter to ensure proper voltage levels.
Use a scan tool to confirm if the TCM communicates over the Controller Area Network (CAN) network.
If the TCM does not respond, reprogramming or reflashing it may be necessary.
Visually inspect the wiring harness and connectors for any damage, and check connector pins for signs of corrosion, bending, or breakage.
This thorough inspection can help pinpoint the issue and guide you towards an effective repair.
