there are 4 o2 sensors and i am trying to id which one, if any, is defective. I tested the ones at the exhaust manifolds. the front one (bank #2?) shows 6.8 ohms between the 2 white wires. If I test between either of the 2 white wires and the two black wires, there is infinite resistance. the book says to check for 6 ohms between the pwr and grd terminals of the sensor, but I am cannnot identify which wire color is which.
I sure dont want to get at those other two sensors, way down behind the steering rack!
The two white wires, at the harnes plug end, show 12.8 v with the key on.
