#1 heated Oxygen sensor is located on the exhaust manifold just before the flange to exhaust pipe inside the engine compartment. Look at the exhaust manifold nearest the firewall (dash). You'll see what appears to be a spark plug like devise that's screwed into the manifold near the flange that attaches to the exhaust pipe. It has an insulated electrical wire extending from its top.
