You probably have blocked passages in the intake manifold. remove the egr and check the port for a clog. you can scrape most of the carbon out with a pick or screw driver and then use some spray carbon cleaner in there. also check the metal exhaust line to the egr

DTC P0332 is for a knock sensor, not egr valve. That's not to say one of the multiple codes you've mentioned wasn't for the egr valve.

What are some of the characteristics the vehicle is showing. By the way, what is the vehicle? In one place it says 1995 contour, in another it says 1995 explorer.

Replace DPFE sensor, reset engine fault codes. The Ford one is a good one and rockauto.com carries Airtex. Sometimes I hear that this change always need replace EGR valve to delet all codes. Test it.

Good luck.

Check eng light on low egr flow replace the egr valve and senore check eng light now says evap and low egr flow?


A very common issue that can cause this code is the EGR valve but most commonly the DPFE Sensor differential pressure feedback egr. For the evap code would make sure no lines may have been disconnected while replacing the egr valve. It is possible the the evap code may be a separate issue.

Engine light on 2002 Explorer. engine code P1400


This may have to do with a bad wiring. Check all the wiring associated with EGR operation. Whenever a computer throws a code about high or low circuit voltage, it is usually attributed to abnormal wiring.
