Symptoms:
- If the code becomes stored, it could disable the exhaust back pressure regulator
- Diminished engine performance
- The engine light will also light up
- Other codes related to the exhaust system or the turbocharger could also be stored
Causes:
- Exhaust gas pressure sensor
- Something could be blocking the tube that runs from the exhaust manifold to the pressure sensor
- Issues with the exhaust gas recirculation system
- Potential issue with the powertrain control module, although this is a quite rare
Possible Solutions:
- Use an OBD-II Scanner to diagnose the vehicle and see if the code returns
- Check wiring and connectors to make sure nothing is shorted or corroded
- Check the exhaust pressure sensor
- Check the tubing that connects the exhaust pressure to the exhaust manifold
