Possible Causes :
- Some aftermarket accessories and performance modifications
- A faulty oxygen sensor. This will set a code in itself, however, a faulty oxygen sensor does not automatically condemn the sensor. The code just means that the sensor signal was not within specifications. An air leak or any of the above will cause an erroneous signal. There is a multitude of O2 codes relating to O2 performance which gives a clue to the problematic area.
- An air leak forward of the DPF will change the sensor readings resulting in the code
