Details of the c0275 OBD Code
C0275 pertains to a problem with the rear wheel speed sensor circuit.
OBD code C0275 means a fault has been detected in the rear wheel speed sensor circuit.
This code is triggered by the Electronic Brake Control Module (EBCM) when it detects an issue with the rear wheel speed sensor circuit.
The rear wheel speed sensor is part of the Antilock Braking System (ABS) and is responsible for monitoring the speed of the rear wheels to help prevent wheel lockup during braking.
When the EBCM detects a problem with the rear wheel speed sensor circuit, it will trigger code C0275.
Mechanic’s Tech Notes
Code C0275 indicates an issue with the rear wheel speed sensor circuit.
OBDII code C0275 indicates a fault with the TCM (Transmission Control Module) power supply.
To diagnose, use a multimeter to check TCM power and ground connections for proper voltage and continuity.
Utilize a scan tool to confirm TCM communication over the CAN network.
Visually inspect wiring harnesses and connectors for any damage, corrosion, or loose connections.
Ensure connector pins are intact.
If all checks out, consider reprogramming the TCM.
FAQ
OBD code C0275 indicates an issue with the Electronic Brake Control Module (EBCM) or Brake Pressure Modulator Valve (BPMV) circuit. Check wiring and connectors for faults.
Common symptoms for OBD code C0275 include ABS warning light on, engine light on. Causes may be faulty EBCM with BPMV, open/shorted harness, poor electrical connection. Fix: Inspect wiring/connectors.
Diagnose and repair OBD code C0275 by checking EBCM with BPMV, harness, and connections for faults. Inspect wiring for damage, broken pins, or corrosion.
Wrap Up
If your ABS warning light is on and you see OBDII code C0275, it may be caused by a malfunctioning rear wheel speed sensor, damaged wiring harness, or poor electrical connection at the sensor.
This can lead to inaccurate wheel speed readings and affect ABS system performance.
To address OBDII code C0275, inspect the rear wheel speed sensor and its wiring for any visible damage.
Test the sensor’s electrical connection and repair or replace any faulty components.
Ensure the sensor is securely mounted and the wiring harness is properly routed to prevent future issues.
