im gonna go try this in a little bit …

but till then … if anyone has anymore info

BUMP … both o2 are showing 12.9ohms on the heater side (at the plug for the sensor)

can anyone get me a wiring diagram for the sensors??

If you go to Autozone they will scan it and the print out will tell you what the code means. Im not sure if this is what your looking for but I hope it helps.

thanks i have a scan tool … i know what the code means … just need a little more insight
