30379, Odd CEL codes..
Posted by jake, Aug-17-02 03:36 AM
Did the key dance a few times and I'm getting some weird codes. Can't find them anywhere in the service manual or Chilton's. Is my ECU crazy?

Codes I got:

12
72
55 (end of codes)

I'll try it once more and make sure..but after 3 times I'm pretty sure that's the codes it's giving me.

72 is one of those oddball codes it throws that aren't in the FSM. It's generally accepted to be a catalytic converter failure code. 12 is "direct power input to the pcm has been disconnected in the last 50 key-ons", but it'll never turn the light on, just an FYI code.

makes sense enuf, no cat on my car. Resetting the ECU took care of it, thanks for your help.
