I want to respond quickly
Expert:  Pete replied 10 months ago.

If you are seeing fault code 2078 this is an indication of a fault with the pressure differential sensor for the diesel particulate filter.If this sensor is failing this causes this issue needing replaced and can be common.I suspect your sensor needs replaced.Make sure the wiring and connections are clean and tight at the sensor and if these are all o.k. then the sensor needs replaced.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,your 5 star rating is appreciated.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
