: P083 Code meaning????

10-29-04, 02:58 PM
As in my earlier post, I have had a re-occuring P083 code. On one list of codes it says, 24X reference code. On another list it says it is a crankshaft to ICM failure. Which one applies to my 1993 STS, with the N*?

I have replaced the crack sensors and the code went off. Then shortly afterward it came back. While driving, the SES light will go off and stay off for a while, then come back on.

I have checked the wiring, the pins in the connectors, the old sensors, the new sensors, removed each coil for cleaning, I'm at a loss.

Replacing the ICM will be about $500.00, which I don't want to do if not neccesary.

HELP!!!! I'm at the end of my rope.

I have the exact problem on my '94 Eldorado. I have replaced both crankshaft sensors, the code is still there. Did you ever get this issue resolved? Please let me know.
