Cadillac Repair: 93 Eldo P025, faulty computer, faulty wiring


Question
I have a '93 Eldorado Sport (270hp 4.6L Northstar). I'm getting error code P025 and P057 (I think it's 57...). I understand the two are very likely unrelated. I know that P025 has to do with the Ignition system where P057 is a tranny circut. I'm asking about P025 right now.

I don't have any symptoms, other than the cars says the problem is there. I tried disconnecting the battery for a while but both codes poped up again. The car seems to run perfectly, no issues. Do I have a busted computer? Thanks for your time.

Answer
You CANNOT erase the CODES by disconnecting the battery .

P025 = 24x signal low in the distributor. What you need to fix this is pictures which are NOT allowed on this person's website.

Possible fault is either:

faulty wiring.
faulty ignition module.
faulty computer.
