Odd OBDII codes

Waffles · Post by **Waffles** » Thu Jan 24, 2008 4:02 am

I was pulling some codes off my Girlfriends 02 Cougar V6 and ran across some I have never seen nor can I find by google

P0305 - Misfire in Cyl 5
P0100 - MAF
P2000 - ???
B2080 - ???
B2004 - ???

Anyone know what they are?

EDIT: I looked up P2080 and it is a stuck IM runner and P2004 is an EGT probe. SO I guess that could be the issue, but why would they come up B?

Pxxxx codes are engine/ trans related
Bxxxx codes are body related
Uxxxx codes are communication codes.

Got it.

I am thinking she has an electrical issue(maybe bad ECU), the codes keep changing. I will reground the car and go from there.

The plug wires were arcing causing the CAS to go nuts throwing all thoes codes. Changed plugs/wires and its all gone.
