I had the Check engine light on for this high voltage on O2 sensor group 1 sensor 2. As it been on and off recently I was wondering if it is just a loose wire? Were is that sensor located exactly?

Depending how many miles are on the car it might just be worth replacing. The sensor is right after the catalytic converter which is right after the exhaust manifold on the car. Its very easy to get to.

Thanks for the reply! I will have a look there dealer told me that the sensor worth about 150$ so it should not be too bad.

I was looking after this today it seem like there is 2 O2 sensor one which is right on top of the manifold and one just after the end of the manifold. I suppose this is the one at the end? I've just had a quote from the dealership at 250$ Anybody know some good online part store where I ould get it cheaper?
