Details of the c0277 OBD Code
C0277 pertains to a fault in the brake pedal position sensor circuit.
OBD code C0277 means a fault has been detected in the steering wheel position sensor circuit.
This code is triggered by the Electronic Brake Control Module (EBCM) based on input from the steering wheel position sensor.
The steering wheel position sensor provides information about the steering wheel angle and rate of rotation to the EBCM for stability control and other safety systems.
Mechanic’s Tech Notes
Code C0277 relates to a fault in the brake pedal position sensor circuit.
OBDII code C0277 indicates a fault with the TCM (Transmission Control Module) connection.
To diagnose, check TCM power and ground using a multimeter.
Verify TCM communication over the CAN network with a scan tool.
Visually inspect wiring harness and connectors for damage, focusing on pin condition.
Look for broken, bent, pushed out, or corroded pins.
Reflash the TCM if needed.
This process helps ensure proper TCM function and resolves the C0277 code.
