C0016
Right Front Wheel Speed Sensor Circuit Range/Performance
Moderatesensor
Overview
The C0016 diagnostic trouble code means the chassis control module has identified a right front wheel speed sensor circuit range/performance problem. This code indicates that a chassis sensor or its circuit is not providing expected readings to the ABS/stability control system. Accurate sensor data is essential for the proper operation of anti-lock brakes, traction control, and electronic stability control, and a fault in this circuit can cause these safety systems to be disabled.
Symptoms
- Brake pedal position reading inaccurate
- Vehicle pulls to one side during braking
- Loss of anti-lock braking function
- Loss of traction control function
Common Causes
- Failed yaw rate or lateral accelerometer sensor
- Damaged or contaminated wheel speed sensor tone ring
- Excessive air gap between sensor and tone ring
- Faulty wheel speed sensor
Diagnosis Steps
- 1Connect an OBD-II scanner and read all stored chassis trouble codes and freeze frame data
- 2Monitor wheel speed sensor signals using scan tool live data while driving
- 3Inspect the affected sensor and its wiring connector for damage or corrosion
- 4Check the sensor air gap and tone ring for damage, debris, or excessive wear
- 5Test the sensor resistance and voltage output with a multimeter; compare to specifications
