Code C0139 Saturn Description
The C0139 diagnostic trouble code (DTC) for Saturn vehicles indicates a problem with the Base Brake System Pressure Circuit/Sensor being too high. The base brake system pressure sensor is responsible for monitoring the hydraulic pressure in the brake system. When the sensor detects that the pressure is too high, it triggers this code to alert the driver or technician of a potential issue.
Common Causes of C0139 Saturn
- Faulty base brake system pressure sensor.
- Contaminated brake fluid causing pressure buildup.
- Blocked brake lines or hoses restricting fluid flow.
- Malfunctioning brake booster affecting pressure regulation.
- Issues with the ABS module or hydraulic control unit.
Symptoms of C0139 Saturn
- Illumination of the brake warning light on the dashboard.
- Increased brake pedal effort required to stop the vehicle.
- Longer stopping distances when applying the brakes.
- Abnormal noises such as squealing or grinding when braking.
- Brake fluid leaks or visible damage to brake components.
How to Fix C0139 Saturn
- Begin by performing a visual inspection of the brake system components, looking for leaks, damage, or contamination.
- Use a diagnostic scan tool to retrieve the specific DTC and pinpoint the exact cause of the high base brake system pressure.
- Test the base brake system pressure sensor for proper operation and replace if necessary.
- Check and flush the brake fluid to ensure it is clean and free of contaminants that could be causing pressure buildup.
- Inspect and test the brake booster, ABS module, and hydraulic control unit for any malfunctions and address as needed.
Cost to Fix C0139 Saturn
The cost of repairing a high base brake system pressure issue can vary depending on the specific cause of the problem and the extent of the repairs needed. On average, the cost of parts for this repair can range from $100 to $300, while labor costs can range from $150 to $400. Overall, the total repair cost for this issue could range from $250 to $700.
