C0210
Rear Axle Speed Sensor Circuit Malfunction
Severesensor
Overview
The C0210 diagnostic trouble code means the chassis control module has identified a rear axle speed sensor circuit malfunction problem. This code relates to a chassis sensor providing incorrect or missing data to the control module. Chassis sensor issues can affect braking, steering, and stability control performance.
Symptoms
- Check Engine Light (MIL) illuminated
- Idle speed fluctuations
- Erratic gauge readings on dashboard
- Poor engine performance
Common Causes
- Incorrect sensor installed
- Faulty PCM/ECM not reading sensor correctly
- Open or shorted sensor wiring
- Physical damage to sensor
Diagnosis Steps
- 1Connect an OBD-II scanner and read all stored trouble codes and freeze frame data
- 2Locate the specific sensor referenced by the code
- 3Inspect the sensor connector for corrosion, damage, or loose pins
- 4Test the sensor output using a multimeter or scan tool live data
- 5Check the wiring between the sensor and the PCM for opens or shorts
