I believe it is located on the exhaust, just before the cytalatic converter, which would be under the truck on the passenger side. Look for what looks kind of like a spark plug sticking out of the Y-pipe just before it connects to the converter. It will have a thin wire coming from the end of it. .

Actually it is before the firewall on the driver side of the engine in the exhaust manifold. You'll be able to reach down next to the oil fill tube and reach it from the engine compartment. It is difficult to reach from below the truck.

The first answer is correct for a 1995 Chevy S10 4x4 with a 4.3 ltr engine. i have one and that is where it is located on mine. need a pipe wrench or adjustable wrench to take it out.
