Is there a way to test O2 sensors?

Is there a way to test O2 sensors, I believe my oil leak soaked the sensor conection and stopped it from working. I am wondering if my sensors are still good or if I have to get another set.

Yes they can, but I haven't actually tried it. Here is a website http://www.mr2.com/TEXT/O2_Sensor.html and I'm sure there are others. I would probably prefer the method where you remove the sensor and heat it up with a torch and take voltage readings. For what they cost it would probably be worth the effort.

thanks man I'll check it out and see what happens.

i did not pop the link up, but i would check values at different temps to see how they are reacting.
ive read of a few folks using the torch method - if you are gonna replace them otherwise, i dont see how you have anything to lose. good luck.
