Hello All,
We bought this car brand new in Sep. 2000. In Nov. 2002 I took this car in for the check engine light being on and they replaced the DPFE sensor. While it was still under thhe factory warranty they replaced it no charge.
Fast forward to today, the engine light is on again and I did a scan of the engine codes and it is only showing P0401, insufficient EGR flow. My research indicates that the most probable cause is the DPFE sensor.
We bought the six year extended warranty on this car when we got it new, so any idea is the DPFE sensor would again be covered again no charge? I forget what the emmissions warranty is on this vehicle, but wouldn't it be covered under that as well?
Thanks, Matt
