Hi,
We have a 1993 Taurus GL with the 3.0 v6. The Check Engine light started lighting on and off about a month ago and now is pretty much on all the time.
I checked the engine codes and am getting 326, 327 and 337. According to a codes list I have, this probably means a bad PFE or DPFE part.
Interestingly enough, this link:
I've talked to two of my local parts people and neither of them can reference "Pressure Feedback EGR Sensor" or "PFE Sensor". What I came up with that they both do sell is named "EGR Valve Position Sensor". There are two types of them available. The two port metal item that is on my car is this one:
Your assistance will be greatly appreciated.
