C0050:08 Code - Right Rear Wheel Speed Sensor Circuit Performance Signal Invalid
Quick Answer
The C0050:08 diagnostic trouble code indicates that there is an issue with the right rear wheel speed sensor circuit's performance signal, which is sending an invalid signal to the vehicle's electronic control module (ECM) or anti-lock braking system (ABS) module. Common causes include Faulty right rear wheel speed sensor, Damaged or corroded wiring harness connecting the sensor to the ECM, Poor electrical connection at the sensor or ECM. 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 C0050:08 Description
The C0050:08 diagnostic trouble code indicates that there is an issue with the right rear wheel speed sensor circuit's performance signal, which is sending an invalid signal to the vehicle's electronic control module (ECM) or anti-lock braking system (ABS) module. The wheel speed sensors are crucial components in the ABS system, as they provide real-time data on the speed of each wheel to the ECM, allowing it to regulate brake pressure and prevent wheel lock-up during sudden braking or slippery road conditions. When the right rear wheel speed sensor circuit performance signal is deemed invalid, it can lead to inaccurate data being sent to the ECM, potentially causing the ABS system to malfunction or not engage when needed. This can compromise the vehicle's braking performance and overall safety, especially in emergency braking situations or adverse road conditions.
Common Causes of C0050:08
- Faulty right rear wheel speed sensor.
- Damaged or corroded wiring harness connecting the sensor to the ECM.
- Poor electrical connection at the sensor or ECM.
- ECM or ABS module malfunction.
- Wheel bearing issue affecting sensor performance.
Symptoms of C0050:08
- ABS warning light illuminated on the dashboard.
- Traction control system (TCS) warning light activated.
- Erratic or inconsistent braking behavior, such as pulsating brakes.
- Increased stopping distance when applying brakes.
- Loss of stability control during cornering or slippery road conditions.
How to Fix C0050:08
- Begin by diagnosing the specific cause of the issue using a professional diagnostic scan tool to pinpoint the faulty component.
- Inspect the right rear wheel speed sensor for any visible damage or corrosion, replacing it if necessary.
- Check the wiring harness for any breaks, frays, or corrosion, repairing or replacing damaged sections as needed.
- Ensure proper electrical connections at the sensor and ECM, cleaning any corrosion or debris that may be affecting the signal.
- If the issue persists, consider testing the ECM or ABS module for faults and replacing if necessary.
Cost to Fix C0050:08
The typical repair costs for addressing a C0050:08 code can vary depending on the specific cause of the issue and the labor rates in your area. In general, replacing a wheel speed sensor can cost between $100 to $200, while addressing wiring harness issues may range from $150 to $300. If the ECM or ABS module requires replacement, the cost can escalate to $500 or more. Additionally, labor rates at auto repair shops typically range from $80 to $150 per hour, so it's advisable to check with local shops for a more accurate estimate based on your vehicle make and model.
