[quote=”college man” post=82220]You would ohm out the two blacks. The with the key on engine
off. Meter on 20 dc volts test for 12volts on the two blacks.[/quote] that would tell me if i am getting power to the 02 sensor from the pcm,right / ETCG was checking the o2 sensor it’s self for resistance unplugged with ohm to see if the o2 was working or dead or to high or ,a new o2 should have about 16 to 20 resistance any more ill be bad thank you[quote=”college man” post=82220]You would ohm out the two blacks.

2 blacks, a white and a blue wire.
One of the blacks is a 12 volt feed wire to the heater the other is grounded by the PCM to energize the heater. The white wire is the ground for the actual sensor and the blue is the signal wire to the PCM.[/quote] on the o2 sensor which wires do i check the with the ohm meter to check if the o2 is good ,,is it the whit and blue that i touch the meter positive and negative ?

will that’s good new that it may be the PC ,mine idles a bit rough ,but no problems wanting to stall ,,,i checked the PVC the vacuum ,that was a while a go ,yes hold the brake and tap the gas and the idle go’s back up, ,turn on the A/C and the idle gos up,there is a bolt on under the throttle body, i can ajust up to bring the idle up,but it seemed to affect how it was starting and shuting off so i turn the bolt back down ,,the guy said that the MFG. computer them that way 2000-30000- i gess ,i clean the throttle body ,,any why thank for now ,no problem in park,,
