Need help with some codes- Please

[DJHA90]

Ok, here are the codes and descriptions. I need some help determining what to do next. New plugs, new distributor cap and rotor. Car has a miss throughout rpm.

157: MAF sensor went below .4 volts during last 80 warm-up cycles

334: DPFE or EVP circuit above the closed limit of .67 volts

624: Electronic presure control solenoid or driver circuit failure

637: TOT sensor circuit above maximum voltage.

I dont even know what an DPFE circuit is or a TOT for that matter.

When I had some wierd codes, the back of my chiltons manual explained the codes, as well as even more detail for some of them

I thought ours used 2 digit codes???...My Actron books states ours are 2

I pulled mine just the other day and got 21/23/34...

No, our cars have 3 digit codes....

Are you sure you are reading the codes right. Because the last code, 637, transmission fluid temperature sensor, is something I believe we do not have, and it only applies to the OBDII mustangs (96+ V8's or 94+ V6)

You need to read them again. Is the CEL light giving you each code twice? You should have seen 157, 334, 624, 637, 157, 334, 624, 637 if the codes you read were correct.

Let us know.

you sure you didn't pull the abs codes(don't think you would andy just checking)...... i think that they are 2 digit........maybe different scanners interpret different, but i have and actron as well..... and i get three digit codes

yep, Scott is right. Foxes have two digit codes and the 94-95's got faster processors with better self diagnostics, hence 3 digit codes.

Im using a digital scanner -- I dont have to count beeps.

Well, honestly, I would disconnect your battery, hit your brakes until the brake lights go out, reconnect, start the car, drive it for 20 minutes, then check the codes again. Maybe some were false codes. Happens all the time.
