testing o2 sensors (1996 grand cherokee)
im fairly certain i have a bad O2 sensor somewhere.. so im wondering what i should do to check them (i dont think autozone or advance will test them)
so.. do i unplug the O2 sensors from above somewhere in the engine compartment, or do i attach the voltmeter directly to the sensors themselvs (it would probably mean more crawling around just to get to them)
if i can just remove the leads from topside and attach them, where would the leads be so that i could get to them?

U cant really test it with a volt meter, and if u dont know where the leads are then u really shouldnt be attempting to test with a volt meter. Y do u think u have a bad o2 sensor, is there a code, running rough, running rich? The only ones that would cause a running issue are the front 02 sensor, which u only have one.

yeah.. i got a code saying "circuit condition (heated oxygen sensor bank 1 sensor 2)"
then below says probably causes are a defective oxygen sensor, or running very lean or rich
got another code that says governor pressure sensor offset voltage too high or low with an internal transmission failure as probably cause (not sure what to do about that... ill feature it in another post)
and in case i forgot to mention, its a 4.0 engine
