Code C1165 Description
The C1165 code indicates a Right Rear Wheel Speed Sensor Input Circuit Failure. This means that the vehicle's onboard computer has detected a problem with the input signal from the right rear wheel speed sensor. The wheel speed sensor is responsible for monitoring the speed of the wheel and sending this information to the ABS system to help control braking and stability. When the sensor fails or its circuit malfunctions, it can lead to issues with the ABS system, traction control, and overall braking performance. If not addressed, this can result in compromised safety and handling of the vehicle.
Common Causes of C1165
- Faulty wheel speed sensor
- Damaged wiring or connectors in the sensor circuit
- Corrosion or debris affecting sensor performance
- Electronic control module (ECM) issues
- Wheel bearing or hub assembly problems affecting sensor operation
Symptoms of C1165
- ABS warning light illuminated on the dashboard
- Traction control system malfunctions
- Inaccurate speedometer readings
- Increased stopping distance
- Wheel locking up during braking
How to Fix C1165
- Begin by locating the right rear wheel speed sensor on the vehicle.
- Inspect the sensor and its wiring for any visible damage, corrosion, or loose connections.
