Code C1165 Lincoln Description
The C1165 diagnostic trouble code (DTC) for Lincoln vehicles refers to a right rear wheel speed sensor input circuit failure. This code indicates that the vehicle's onboard computer has detected a problem with the input signal from the right rear wheel speed sensor. The wheel speed sensors are crucial components of the vehicle's anti-lock braking system (ABS) and traction control system, as they provide real-time data on the speed of each wheel to the ABS module.
Common Causes of C1165 Lincoln
- Faulty right rear wheel speed sensor
- Damaged or corroded wiring leading to the sensor
- Loose or disconnected electrical connections
- Malfunctioning ABS module
- Tone ring issues on the wheel hub
Symptoms of C1165 Lincoln
- Illuminated ABS warning light on the dashboard
- Traction control system warning light may be illuminated
- Erratic speedometer readings or speedometer not working
- ABS system engaging unexpectedly or not engaging at all
- Grinding or clicking noises when braking
How to Fix C1165 Lincoln
- Use a diagnostic scanner to retrieve the specific DTC and confirm that the issue is related to the right rear wheel speed sensor input circuit.
