Unknown ECU Factory Code

[GreenDemon]

I put a new (used) ECU in my 92 Eagle Talon TSi AWD Turbo. It has been showing a CE light ever since. No one has ever been able to pull any codes from this car, even with the previous ECU. Not even a Chrysler dealer.

I finally found someone who was able to get a code from this ECU, but the code does not exist. According to the mechanic, his list (and all I've seen) start at number 11 and he states this a factory code never released on a list to the mechanics. He said I should call and ask the dealer. The dealer has no clue either. The code is a 02 pulled with an OBD1 scanner.

Does anybody know what this code means?

True though, they do begin with a "1"...

(bet it's a 12 meaning your MAF isn't doing it's thing)

ECU Code Checking check this site out for retrieving codes ... works good with an analog VOM, or a 12v beeper..

OBD-1 scanners sometimes aren't the best way to go...

Will have to get the 12v. I suck at testing for myself. Only so much this girlie can do and electrical is my weakest link. Not to mention as of this week, its giving me new issues. I've noticed it was surging rpm's when I switched gears and its losing its power. As of tonight, it was doing 4000 rpm's in 4th gear at 60 mph. It's like the turbo has died and there's no pick up. It's just revving really high when I go through the gears. Not sure how else to explain it. Before, when I would change gears, it had pull to it. Now it doesn't. Love this car, but can't keep spending the money to find a problem when there's nowhere to begin from. It's like a needle in a haystack.

11 is the fault code for a bad O2 sensor.
Have you pulled and inspected the ECU for capacitor leakage?
Made sure it's the right ECU for the car?
