Anyway to test which O2 Sensor is bad before I start buying?

What reading should I be looking for on my Ohm Meter?

I noticed the good ones are pretty expensive. Want to make sure I get the right one replaced.

 

You would really need a laptop with a program to read the real time values with the car running.


We have tried to figure out how to test like on the older cars with a volt meter but never get anything from the sensor with the volt meter.

 

I was hoping you were not going to say that. [&o]

I was assuming the same thing.

Thanks for the help.

I guess I'll dish out the cash and replace both of them. [:@]
