I've got check engine "PO136 code heated oxygen sensor bank 1 sensor2", I have checked 14 ohms resistance on terminals +B and HT of the sensor - as per alldata manual it should be between 11-16 ohm.
OBDII live data shows zero voltage from the sensor though.
Is the sensor gone?
The truck is 2000 4Runner SR5 V6 3.4L auto single cat. converter.
If I need a new sensor what brand is to go with, Denso or NGK?

Thanks.

 

Is that the front or rear O2 sensor? I have a spare front O2 sensor from my truck for sale, replaced it while trying to figure out a lean condition that turned out to be an exhaust leak. Still worked great but was too late to return it.

I would let it go for $25 shipped.

And yes it does sound like a bad O2 sensor.

 

I went with the Denso one from URD it works

 

TA- this is a rear sensor. I will go with denso, is 234-4162 correct #?
What is URD?

Thanks,

 

Not sure on the part number, i have not had to touch the rear sensor.
