Someone else posted a complete O2 failure on this forum before, I think that he had them installed by someone else or something like that and when they put them in, they never hung the wires back up correctly and the insulation burned off the wires and shorted them all out. Just a thought, something to look at maybe??? Good Luck, tell us what fixes this when you get it figured out.

 

Ok, here's an update! Nothing....

I replaced (under warranty) all 4 O2 sensors and nothing changed at all...Light stayed on. I have noticed that with in 15 miles of resetting the codes, the 0150 registers first. then about another 30 or so, the other codes come back on (don't relcall them off the top of my head, have them listed in my first thread.)

I'm going to test the leads (Rove side, not the O2) with a multimeter. Does anyone know the procedure for this?

THanks for all your time.
