I'm having trouble with DTC 332 on my 1995 F150 5.0. When I purchased the truck it was plagued with 7 or more DTC's. I took the upper and lower manifolds off and had the local machine shop dip and clean both manifolds. I reassembled with brand new injectors, complete tune up and new egr valve and tube from lower to upper. I'm still down to just DTC 332. I then realized that the New EGR valve was not holding vaccuum so I purchased a junk yard EGR which does. Seems to idle better. I've replaced EVR solenoid as well. I've checked the vaccuum hoses with vaccuum pump and they seem to be fine. I keep reading about PFE/DPFE sensor as being a possible problem, yet I'm unable to locate it on my truck. I'm not sure if it has one. The diagram under my hood doesnt not indicate a PFE/DPFE in it. Do you know if it has one and where I might locate it? I know my F150 has a crossover pipe in the rear from cylinder head to cylinder head. Is it possilbe that it's the problem, clogged? Or leaking? I'm running out of Ideas.
have the same problem?
