It's in the middle of the rear exhaust manifold, between the firewall and the engine, just above the flange the exhaust system connects onto. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Good morning.

I attached a picture for you to view. That is the sensor in question.

The sensor is one of many possibilities for this code. Below are the possibilities.
