I recently got the wonderful check engine light on my 94 XLT to come on. I pulled the codes from it and got the following:
KOEO
335 PFE or DPFE sensor out of self-test volt range
522 Not in park or neutral during test (not really important )
CM
332 EGR valve not opening not detected
So, after reading all of the posts on the subject I could find, my question was should I try and clean the EGR valve first, and if so how would I do that, or do I go and replace the DPFE first and hope that was the original problem?
Any help would be appreciated.
Thanks
