Where would you find the crankshaft position sensor for a Chevrolet 2000 tracker?

on the driver side top be hind valve cover

5/30/12 - The 2000 Chevy Tracker may have one of 2 engines - 1.6 or 2.0 liter. The 1.6 version has an easily accessible crankshaft position sensor at the rear of the cylinder head on the driver's side. But the 2.0 engine requires the transmission & flywheel to be removed. That's a big difference in effort & cost.
