Code C128C Description
The C128C diagnostic trouble code (DTC) indicates an ABS Regenerative Axle Pressure Sensor Offset Error. This error occurs when the sensor that monitors the pressure in the regenerative braking system of the vehicle detects an offset error. The regenerative braking system is responsible for capturing and storing energy that would otherwise be lost during braking, helping improve fuel efficiency and overall performance.
Common Causes of C128C
- Faulty regenerative axle pressure sensor
- Wiring or connection issues related to the sensor
- ABS module malfunction
- Calibration errors in the braking system
- Damage to the regenerative braking components
Symptoms of C128C
- Illuminated ABS warning light on the dashboard
- Unusual braking behavior, such as pulsating or inconsistent braking
- Increased stopping distance
- Decreased stability and control during braking
- Strange noises coming from the braking system
How to Fix C128C
- Diagnose the issue using a diagnostic scanner to retrieve the error code and pinpoint the source of the problem.
- Inspect the regenerative axle pressure sensor and its connections for any visible damage or corrosion.
- Test the sensor's functionality and calibration to determine if it needs to be replaced.
- Replace the faulty sensor or repair any wiring/connection issues if necessary.
- Clear the error code from the vehicle's system and perform a test drive to ensure the issue has been resolved.
Cost to Fix C128C
The typical repair costs for addressing an ABS Regenerative Axle Pressure Sensor Offset Error can range from $200 to $500, depending on the specific cause of the issue and the cost of parts and labor. It's important to note that the actual cost may vary based on the location of the repair shop, the make and model of the vehicle, and the expertise of the technician. Additionally, diagnostic time and labor rates can impact the overall cost of the repair, so it's recommended to obtain quotes from multiple auto repair shops to find the best price.
