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?
