The wheel speed sensor is a crucial component of the vehicle's anti-lock braking system (ABS) and traction control system. It is responsible for monitoring the speed of the wheel and providing this information to the ABS control module.
Common Causes of C1165 Mercury
- Faulty right rear wheel speed sensor
- Damaged or corroded wiring/connectors in the sensor circuit
- Absence of tone ring on the wheel hub
- Malfunctioning ABS control module
- Issues with the vehicle's power or ground circuits
Symptoms of C1165 Mercury
- ABS warning light illuminated on the dashboard
- Traction control system malfunction indicator
- Inconsistent or inaccurate speedometer readings
- Increased stopping distance during braking
