wierd dpfe situation - 08/27/06 05:03 PM
'95 zetek 2.0 here
A couple days ago I got code 332 Insufficient EGR flow. I cleaned the TB and passages and the EGR itself was new so I decided to try a new dpfe. The old one was silver metal and the new one is black plastic.
Well the new DPFE stopped throwing 332, but throws 335 instead - "PFE sensor circuit voltage out of Self-Test range". There is no longer a lighted CEL when driving - but when I check for codes I get 335. Interestingly, when I reset the pcm and check for codes again, without even having driven the car since resetting, I get 335 - so it must register without even turning on the engine.
Because this was confusing me I picked up yet another dpfe and tried it - I get the same situation - no lighted CEL, but 335 is there. Anyone know what the deal is here?
