Hmmm... the o2 sensor diagnostic?
The first thing I did was hooked the air/fuel gauge to the wire at the ECU and got the strange reading.
Secondly I verified that the wire I was connected to was the same as the one at the o2 sensor using the ohmmeter. Check.
Next I ran a wire directly to the o2 sensor to a voltmeter in the car. Same result.
What diagnostic are you refering to?
