Code C0050 Pontiac Description
The C0050 diagnostic trouble code for Pontiac vehicles indicates a problem with the right rear wheel speed sensor circuit. The wheel speed sensor is a crucial component of the vehicle's anti-lock braking system (ABS) and traction control system. This sensor is responsible for monitoring the speed of the right rear wheel and sending this information to the vehicle's electronic control module (ECM). The ECM uses this data to regulate the ABS and traction control systems, ensuring optimal braking performance and stability.
Common Causes of C0050 Pontiac
- Damaged or corroded wheel speed sensor wiring
- Faulty wheel speed sensor
- Poor electrical connection or wiring harness issues
- Sensor contamination from dirt, debris, or brake dust
- ECM or ABS module malfunction
Symptoms of C0050 Pontiac
- ABS warning light illuminated on the dashboard
- Traction control system warning light activated
- Erratic or inconsistent braking behavior
- Vehicle stability issues, especially during braking or cornering
- Increased stopping distance or difficulty stopping in slippery conditions
How to Fix C0050 Pontiac
- Begin by diagnosing the specific cause of the right rear wheel speed sensor circuit issue using a diagnostic scan tool.
- Inspect the wiring harness and connections for any signs of damage, corrosion, or loose connections. Repair or replace as needed.
- Test the right rear wheel speed sensor for proper functionality. Replace if faulty.
- Clean the sensor and surrounding area to remove any dirt, debris, or brake dust that may be affecting its performance.
- Clear the diagnostic trouble codes from the ECM and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix C0050 Pontiac
The typical repair costs for addressing a C0050 Pontiac code related to the right rear wheel speed sensor circuit can range from $100 to $300, including parts and labor.

My code says c0050-00 is that another part cause all i see are the first part and if the exam was bas wouldn't it so another code or all the wheels sensors as faulty ?
-
C0050-00 is the full code, but the important part is still “C0050,” which points to the right rear wheel speed sensor circuit. The “-00” at the end is just a sub-code that usually means “no additional information.” It doesn’t change the part you look at.
If the ABS module itself were bad, you would normally see multiple wheel sensor codes or communication codes — not just one wheel. A single C0050 almost always means:
• the right rear wheel speed sensor is faulty,
• the sensor connector is loose or corroded, or
• the tone ring/bearing at that wheel has failed.So yes, it’s still that one wheel. Start by checking the sensor and wiring at the right rear hub. If the wiring looks good, the hub bearing (with built-in tone ring) is often the actual problem on these.
