Code C1175 Mercury Description
The C1175 diagnostic trouble code (DTC) for Mercury vehicles indicates a Left Rear Wheel Speed Sensor Input Circuit Failure. This means that the vehicle's onboard computer has detected an issue with the input signal from the left rear wheel speed sensor. The wheel speed sensor is a crucial component of the vehicle's anti-lock braking system (ABS) and traction control system. It measures the speed of the wheel and sends this information to the ABS module to help prevent wheel lockup during braking and improve overall vehicle stability.
Common Causes of C1175 Mercury
- Damaged or corroded wiring connecting the wheel speed sensor to the ABS module
- Faulty wheel speed sensor
- Loose or disconnected electrical connectors
- Issues with the ABS module or related components
- Water or debris intrusion affecting the wheel speed sensor operation
Symptoms of C1175 Mercury
- Illumination of the ABS warning light on the dashboard
- Traction control system malfunction or warning light activation
- Increased stopping distance during braking
- Unusual noises coming from the wheel area
- Vehicle stability issues, especially during turns or on slippery surfaces
How to Fix C1175 Mercury
- Begin by visually inspecting the wiring harness and connectors for any signs of damage, corrosion, or disconnection. 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.
- Clear the DTC from the vehicle's computer using a diagnostic scan tool.
- Test drive the vehicle to ensure that the ABS, traction control, and stability control systems are functioning correctly.
- If the issue persists, further diagnostics may be required to identify any underlying problems with the ABS module or other related components.
Cost to Fix C1175 Mercury
The typical repair costs for addressing a Left Rear Wheel Speed Sensor Input Circuit Failure can range from $150 to $300, including parts and labor. However, the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. It is advisable to check local rates for a more precise estimate. Keep in mind that rates in metropolitan areas or at dealerships may be higher, while independent shops often charge less.

Frequently Asked Questions about C1175 Mercury Code
1. What does the OBDII code C1175 mean for a Mercury vehicle?
C1175 indicates a Left Rear Wheel Speed Sensor Input Circuit Failure, meaning the vehicle's ABS module is not receiving a proper signal from the left rear wheel speed sensor.
2. What are common symptoms of the C1175 code?
Common symptoms include the ABS warning light or traction control light being illuminated, erratic ABS operation, reduced braking performance, or the speedometer functioning improperly.
3. What causes the C1175 code to be triggered?
This code can be caused by a faulty left rear wheel speed sensor, damaged wiring or connectors, a dirty or damaged tone ring, or a malfunctioning ABS module.
4. How can I diagnose the C1175 code?
Start by visually inspecting the left rear wheel speed sensor, its wiring, and connectors for damage or corrosion. Use a multimeter to test the sensor's resistance and check for proper voltage at the connector.
5. Can a dirty tone ring cause the C1175 code?
Yes, a dirty or damaged tone ring can prevent the wheel speed sensor from reading accurately, which can trigger the C1175 code.
6. Is it safe to drive with the C1175 code active?
While the vehicle may still be drivable, the ABS and traction control systems may not function properly, which can compromise safety, especially in slippery conditions.
7. How do I fix the C1175 code on a Mercury vehicle?
Repairs may include cleaning or replacing the left rear wheel speed sensor, repairing or replacing damaged wiring or connectors, or replacing a faulty tone ring or ABS module.
8. How much does it cost to repair the C1175 code?
The cost varies depending on the exact issue, but replacing a wheel speed sensor typically costs $100-$300, including parts and labor.
9. Can a faulty ABS module cause the C1175 code?
Yes, although less common, a malfunctioning ABS module can fail to process the sensor signal properly, leading to this code.
10. Will clearing the code fix the issue permanently?
No, clearing the code without addressing the underlying problem will only temporarily remove the code. The issue must be diagnosed and repaired for a permanent fix.
