Code Help!

[billbosc]

Figured I would just start a new thread about these codes instead of it piling up in my topend thread. I got all these codes and what they mean. But what I dont know is which ones are important/a must fix. Or how to even fix them lol. So I wil put them here and see if there is anyone that can help..

11- System Pass
21-ECT sensor out of self test range--I read this is probalby due to the motor being cold when tested
29-Insufficient input from vehicle speed senor (vss)
34-1. Pressure feedback (PFE) sensor voltage out of test range
2.Exhaust back pressure high/ PFE circuit voltage high
44- air injection control system failure
63- throttle positioner circuit below minimum voltage
87- fuel pump circuit failure
94-torque converter clutch solenoid circuit failure
95-fuel pump secondary circuit failure

If there is other threads with these codes and help please shoot me in that direction. a search didnt turn up much that I could find quickly. and google is cluttered with a bunch of mess. If I have to sift through a bunch of stuff I have to sift through a bunch of stuff.

Im guessing this was some sort of hacked up car?? Details regarding the car and its symptoms please

To be honest it just runs lean and idle surges at stop signs and lights sometimes. It has a
Superharger hooked up.

Is 63 saying he needs a new tps?

EEC-IV codes 86-93 - The Mustang Source - Ford Mustang Forums
Start by getting a new throttle position sensor from the parts store to address code 63. It's not super expensive and easy to replace. A new one should help fix driveability issues. Make sure the butthole who had it before you didn't "whaller out" the holes where it mounts so he could reach the "magic 1 volt." If he did you might have to get a washer or something so It line up and fit right.
Code 29 you can live with.

Need more details on the car....

What year? Is this a 4-cyl converstion to a 5.0? IS it a MAF-conversion car?

Some of those codes are common with 86-88's converted to MAF that don't do the VSS or fuel relay wiring.


Code 63 doesn't suggest a bad TPS. It could be a TPS sensor that is set way out of the 0.5-1.1V range that is accepted. It could just need an adjustment.

Need background info on the car first before I speculate further.

Did you do the engine running codes as well?


Code 34 is an EGR related code (is it present) and code 44/94 are Oxygen sensor codes (are they present) so some of your code definitions are incorrect

New TPS? Who said that?.......................................oh.................nevermind.. Get a DVM and see if you can get it within range first.

X1000 on more info needed before you start throwing parts at it.
