Most O2 sensors are in the Exhaust pipe running from the back of the manifold. It is silver with a single black wire running to it. It threads into the exhaust pipe like a spark plug and can usually be accessed from under the hood. Happy Wrenching.
In the 1989 Grand Prix, the oxygen sensor is in the tail pipe. Look for a wire that is plugged into both the tail pipe and the undercarriage of the vehicle.
Crank sensors are always located on the camshafts. The 1989 Pontiac Sunbird crank sensor is located on the head of the engine towards to end of the camshaft.
