C1175 Lincoln Code - Left Rear Wheel Speed Sensor Input Circuit Failure
Quick Answer
The ABS module receives wheel speed readings from each wheel speed sensor and processes this information to determine if an ABS event is necessary. Common causes include Faulty Left Rear Wheel Speed Sensor, Left Rear Wheel Speed Sensor harness is open or shorted, Left Rear Wheel Speed Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C1175 Lincoln Description
The active wheel speed sensor generates a signal that is sent to the ABS module. The wheel speed sensor circuitry connects to the ABS module through 2 wires and a connector at each wheel speed sensor. When the ignition is turned to the RUN position, the ABS module carries out a self-test by sending a reference voltage to all of the wheel speed sensors through their circuitry to determine if they are functional.
The ABS module continuously monitors and compares the rotational speed of each wheel and when it detects an impending wheel lock, modulates brake pressure to the appropriate brake caliper. This is accomplished by triggering the hydraulic control unit (HCU) to open and close the appropriate solenoid valves. Once the affected wheel returns to normal speed, the ABS module returns the solenoid valves to their normal position and normal (base) braking resumes.
What are the Possible Causes of the DTC C1175 Lincoln?
- Faulty Left Rear Wheel Speed Sensor
- Left Rear Wheel Speed Sensor harness is open or shorted
- Left Rear Wheel Speed Sensor circuit poor electrical connection
