Code 65.
I pulled a code 65, O2 censor circuit. Is that the fuse? If so where is it?

Re: Code 65.
check ohm resistance from the two heater terminals on the o2 sensor harness (o2 sensor side). they should measure 10 - 40 ohms. if not, sensor is no good.
there should also be battery voltage with the ignition key set on the ON position (12v + or - 2 volts) on the engine wire harness side. if not, there is a break in the circuit. check connection from ecu to sensor to main relay. i dont really remember all the diagrams from the top of my head, but, i believe only the primary o2 sensor uses the main relay not the secondary.
