replaced egr valve twice but keeps coding what else can I do?
Hi there
This code does point to a problem with the EGR position sensor. This doesn't mean the sensor isn't working, it can also mean there wiring is bad. Also, check for a blockage on the egr. If it's blocked then the car won't know when it opens.
