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.

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

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.
