Going over codes

[SnoSho]

Ok finally had the codes pulled againover at Autozone. What do guys think, MAF, TPS, PIP, O2's running lean & rich (Figure from the MAF), Thermostat reading 240.

Where should I start, pip is the damn Crank right? I'm gonna order a new MAF, t-stat and TPS, I havn't been getting the no tach/ stalling thing from a CPS or maybe my memory isn't working this morning so is their anything that could bring that code without it going bad?

Would you be so kind as to post the actual codes that were read? That is helpful in the diagnosis of the problem(s).

You would ask me that Scott I'm going of the notes I wrote as he looked them up his notes are all over the place with hash marks and frozen pen restarts? Heres what I can see.

117
172
173
176
177
211
34 (Not possible on a 94 a 2 digit right?)
128
I also can't find the other two codes he pulled right away (MAF and TPS voltage too high) Unless one of those up there is them, I'm at work still but when I get home I can look them up.

Do yourself a favor and use the old paper clip and CEL to get your own codes.

It isn't difficult, but it takes some practice to get the timing down right.

You have plenty of codes with which to practice.

A number of those sensors all use the same reference voltage. My guess would be a bad connection in the supply circuit before all those sensors (MAF, TPS, ECT, MAP/BP, etc) would have gone bad.

You should really clear all the codes including the continuous codes, then start again. Run the quick test and record codes each time the CEL comes on.

Your codes of 172/173 and 176/177 are continuous codes and are directly contradictory to each other. They might mean you have bad O2 sensors, or they might mean you have a vacuum leak or other control problem.

Far better to start with a clean slate.

Disconnect the battery for a few minutes, then reconnect it. Perform the Idle relearn process, then drive the car. Extract codes as the CEL dictates.

Good luck.

Relearn thats where you pull the battery and turn on everything to drain the charge before turning it back on right?

Ya looked them up, always lean and always rich thats interesting with new O2's at least they are still look new maybe I'll replace them anyway.

Taking the car in this week to decarbon it then I'll deal with the wear sensors I ordered from SHOnut. I'm thinking I shorted something out when the coolant blew and gave everything a nice bath. Just wish I had a clue where to start morons at Ford (Not the dealer I normal use, couldn't get in at the Motorsports dealer.) Told me it was "all fixed" when I get a CE light within a block I knew it wasn't fixed and no way in **** it was going back there.
