Code C1175 Description
The C1175 diagnostic trouble code (DTC) indicates that there is a failure in the left rear wheel speed sensor input circuit. This sensor is responsible for monitoring the speed of the left rear wheel and transmitting that information to the vehicle's electronic control module (ECM) or anti-lock braking system (ABS) module. When this sensor fails or malfunctions, it can have a significant impact on the vehicle's performance and safety.
Common Causes of C1175
- Damaged wiring or connectors leading to the left rear wheel speed sensor
- Failed left rear wheel speed sensor
- Corrosion in the sensor's mounting location affecting signal transmission
- ECM/ABS module malfunction affecting sensor input
- Physical damage to the sensor or its wiring due to road debris or impact
Symptoms of C1175
- Illuminated ABS warning light on the dashboard
- Traction control system malfunction indicator
- Inaccurate speedometer readings
- Increased stopping distance during braking
- Unusual noises from the wheel area
How to Fix C1175
- Begin by diagnosing the specific cause of the left rear wheel speed sensor input circuit failure using a scan tool to read the DTCs and perform a visual inspection of the sensor and surrounding components.
- Inspect the wiring harness and connectors for any visible damage, corrosion, or loose connections. Repair or replace any damaged components as needed.
- Test the left rear wheel speed sensor using a multimeter to check for proper resistance and signal output. Replace the sensor if it fails the test.
- Clean the sensor mounting area to remove any corrosion or debris that may be affecting signal transmission.
- Clear the DTC from the ECM or ABS module memory using the scan tool after completing the repairs and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix C1175
The typical repair costs for a left rear wheel speed sensor input circuit failure can vary depending on the specific cause of the issue and the vehicle's make and model. In general, replacing a wheel speed sensor can cost between $100 and $200 for parts, with additional labor costs ranging from $80 to $150 per hour. The total repair cost, including diagnosis time and potential additional repairs, could range from $200 to $500.
