1991 Mustang GT

Wife said car(and I verified) that she lost speed control, got a check
engine light, and the transmission doesn't want to respond correctly (ex.
slow to engage when accelerating after having slowed down for an off ramp,
or speeding up to pass).

First engine scan gave the following errors:

KOEO Codes-
23 Throttle Position Sensor is out of range
Memory Codes-
31 EGR valve position or exhaust pressure transducer sensor voltage low
63 Throttle Position Sensor voltage too low or grounded
KOER Codes-
12 Cannot control RPM during self check or Idle Speed Control Problem
23 Throttle Position Sensor is out of range

Cleared codes, unplugged TPS and scanned a second time and got these errors:

KOEO Codes-
98 Electronic Pressure Control driver failure in control module (or hard
fault)
63 Throttle Position Sensor voltage too low or grounded
Memory Codes-
11 System Pass
KOER Codes-
12 Cannot control RPM during self check or Idle Speed Control Problem
23 Throttle Position Sensor is out of range

It's having issues obviously, but it's the Memory code 11 that throws me.
That seems to signify that the electronics are fine but the 98 seems to
mean everything is screwed. This car has some age on it but was kept (I
though well) by the previous family member. Could the TPS, EGR and Speed
Control all be bad at the same time? Or am I looking at a bad ECU supplying
bad voltage to the sensors? I thought I was looking at replacing an ECU at
first. All the parts put together aren't too much to replace, but I'd
prefer a simple fix. Yes, it passed a wiggle test.

Re: 1991 Mustang GT

Well, the first thing i'd do is borrow or buy a dvm and confirm 5 v and grd
at the TPS and that the sense wire varied.

If you've had the car a while and never changed the TPS, it's probably due
anyway.

Do you have any better advice, or are you just going to keep trolling?


Put up or shut up, you probably don't know the first thing about fixing
his problem. Master Ford tech my ass.

Re: 1991 Mustang GT

Leave Hurricane alone and he'll go away. He was in the ford group and now
he's trolling in here. He knows shit...just cuts and pastes
answers.......not even a tech as you guys can see. Probably some little shit
kid taking auto shops in high school, and has no life.

Re: 1991 Mustang GT

What's sadder (for hurc) is that he probably is some 45 year-old with a
kid in college.

lmfao

WTF are you talking about, first I'm not a mechanic by trade. Second,
there is nothing wrong with my car. When there is I have a 7 year warranty
so i don't have to "get some certification". All that aside, I still bet I
know more about the internals of my vehicles than you ever will.
