95 exploder : 3 CODES . . . 114 327 636 HELP ! ! !
 

ok, i have a 95 explorer 3 codes came up today.

114 - IAT (intake air temp) out of range
327 - EGR feedback signal low (dpfe sensor?)
636 - transmission oit temp out of range.


let me explain my situation....
i was driving my explorer and then all of a sudden, from a stop light to acceleration it would not shift into 2nd gear... it was kinda like it was a stick shift and i was revving it in 1st..

well, i slightly let go of the pedal and it shifted fine. . . but almost seemed like 3rd gear instead of 2nd.

anyways, it does it permanently now, and so i have to drive it from stop to go for until about 3k rpm and then i slightly let of and itll shift. it is still dependable and all other higher gears shift smoothly(like when im on freeway passing someone) .

ive read tons of forums and people that have that problem have their transmission replaced, but their problem seems more severe( like they wont be ablt to get it out of first at all. )

PLEASE HELP ! ! ! i guess i can start by draining tranny fluid and replacing air filter? i have no idea. it seems like a transmission issue but who knows....
2 codes sorta deal with air. thanks guys!!!

Could be a VREF issue, all three of those run off VREF if I remember right. Could also be a ground problem.

I give, what is a VREF?

Voltage reference..
