Code C1275 Description
The C1275 diagnostic trouble code indicates an abnormal change in the output signal of the front right speed sensor in the vehicle's anti-lock braking system (ABS). This sensor is responsible for monitoring the speed of the front right wheel and relaying this information to the ABS control module. When the sensor detects an abnormal change in the wheel speed, it can cause the ABS system to malfunction, potentially leading to issues with braking performance and stability control.
Common Causes of C1275
- Front right speed sensor malfunction
- Damaged or corroded wiring/connectors
- Magnetic interference affecting sensor readings
- Sensor misalignment due to improper installation or suspension damage
- ABS control module failure or communication issues
Symptoms of C1275
- ABS warning light illuminated on the dashboard
- Increased stopping distances during braking
- Brakes locking up or pulsating during braking
- Loss of traction or stability control in slippery conditions
- Unusual noises coming from the ABS system during operation
How to Fix C1275
- Begin by diagnosing the specific cause of the abnormal signal from the front right speed sensor using a scan tool or diagnostic equipment.
- Inspect the sensor, wiring, and connectors for any visible damage, corrosion, or loose connections. Repair or replace as needed.
- Check for any magnetic interference near the sensor that could affect its readings. Remove any sources of interference.
- Ensure the sensor is correctly aligned and mounted to the wheel hub. Adjust or reposition as necessary.
- Clear the trouble code from the ABS system and test drive the vehicle to verify proper sensor operation and ABS system functionality.
Cost to Fix C1275
The typical repair costs for addressing the abnormal change in output signal of the front right speed sensor can range from $150 to $400, including parts and labor. However, the final cost may vary depending on the vehicle make and model, the extent of the issue, and the specific repair shop rates. It's recommended to consult with a qualified mechanic or repair facility for an accurate estimate based on your vehicle's individual needs.
Tech Notes for C1275
If there is iron powder sticking to the rotor, this will result in a malfunction, so confirm that the rotor is not contaminated with foreign material before replacing the sensor.
Check the speed sensor signal after cleaning or replacement.
On most vehicles, the Front Speed Sensor Rotor is incorporated into the Front Axle Hub Sub-Assembly. If the Speed Sensor Rotor needs to be replaced, replace it together with the Front Axle Hub Sub-Assembly.
