engine trouble 87 Aries

[Jon1dotcom]

I have a 87 Aries (2.2 ) with aprox 128000 miles. The transmission is leaking on the ground (slowly -- bad seal somewhere) but that is going to be fixed in a few days. The problem I am currently having is this. Two days ago (Sat) I replaced the fuel injector in hopes of clearing up engine code 26 "Injector 1 peak current" (according to Hayes repair manual). I've had code 26 since I've had the car (4 years) but I couldnt seem to figure out how to fix it (btw changing the injector didnt help), but the engine never seemed to run rough. After checking the codes today I got the following codes 23, 24, 26.
23 is "Throttle body temparature voltage too high / or too low.
24 Throttle position sensor voltage to high / low
26 Injector 1 peak current
of course 55 also comes up, but this is end of tests code.

the TPS was replaced recently (within the year), so I'm not sure why I'm getting 24. Enginge is running rough now, although acceleration is better since replacing the injector.

Does anybody have any suggestions? (besides how to blow up the car LOL). When I replaced the injector, it didnt come with the electrical connection for it, so that part wasnt replaced (however it didnt seem to be worn out / frayed / cracked etc).

If at first you don't succeed --- skydiving isn't for you.

with that many error codes, you could have a bad module.

Is that something a dodge dealer could test? (to see if the module is bad) Pardon my ignorance, but which module in particular are you reffering to?

Yea kinda wonder the same here. What module? It could very well be the Logic Module but then there are 2 Modules on this car. There is a Logic Module bottom right kick panel. EFI Power Module left front corner under hood. From looking at wiring diagrams , 23 -24 go to Logic Module. The injector goes to Power module.
The tps and throttle body sensor share the same ground wire. May want to check that.

sorry for not being more specific, the Powertrain Control Module. It should be mounted on the driver's side fenderwell and have 14 wires going to it.

Not sure if I found the problem or not. As I took the battery out from the car (I usually just disconnect the Neg) I discovered a (what I think was) a open ground wire. Fixed that and cleaned up the rest of the engine (dirt / small leaves etc). Will report back findings in a few days (codes)

After fixing the wiring poroblem (ground wire had indeed broken) I reset the computer (let set disconnected from battery for a good 7 - 8 hrs) Current codes showing up now are:

12: Number of key-ons since last fault or since faults were erased.
In this case, this is expected (computer has just been cleared)

15: No vehicle speed signal
Hayes: "No distance sensor signal detected during eoad load conditions" My guess is that this is a electrical problem & not the sensor itself. Will check the (connector) wires for frayes / breaks.

55: End of test -- expected.
