Code P245E GMC Description
The P245E GMC code refers to the Diesel Particulate Filter (DPF) Pressure Sensor 'B' Circuit. This code indicates that there is an issue with the pressure sensor that monitors the diesel particulate filter in the vehicle's exhaust system. The DPF is responsible for capturing soot and other particles from the engine's exhaust to reduce emissions. The pressure sensor helps the engine control module (ECM) to monitor the efficiency of the DPF by measuring the pressure before and after the filter.
Common Causes of P245E GMC
- Faulty DPF pressure sensor
- Wiring or connector issues related to the sensor
- Clogged or damaged diesel particulate filter
- Software or calibration issues with the ECM
- Exhaust system leaks or restrictions
Symptoms of P245E GMC
- Check engine light is illuminated
- Decreased fuel efficiency
- Decreased engine performance
- Excessive smoke from the exhaust
- Diesel particulate filter regeneration issues
How to Fix P245E GMC
- Perform a diagnostic scan to confirm the P245E GMC code and identify the specific issue.
- Inspect the DPF pressure sensor, wiring, and connectors for any visible damage or corrosion. Replace or repair as necessary.
- Check the diesel particulate filter for clogs or damage. Clean or replace the filter if needed.
- Clear the code from the ECM memory using a diagnostic scan tool.
- Test drive the vehicle to ensure the issue has been resolved and the check engine light does not reappear.
Cost to Fix P245E GMC
The typical repair costs for addressing the P245E GMC code can vary depending on the specific cause of the issue and the labor rates at the auto repair shop.
