replacing the camshaft positioning sensor on 2000 Pontiac Bonneville

how do i replace the camshaft positioning sensor...i cannot find where it goes

Asked by for the 2000 Pontiac Bonneville
The camshaft sensor is located at rear side of the water pump pulley. The sensor is under $100 and takes under an hour to install. Check that the wiring harness has not become damaged or fouled by the water pump pulley.
