The location of the camshaft position sensor on a 2002 Chevy Trailblazer depends on the vehicle's engine type. A Trailblazer with a six-cylinder engine has the sensor located on one of the cylinder heads, while a V8 engine has the sensor mounted on the engine block. The procedure for removing and installing a camshaft position sensor is essentially the same, regardless of where it is mounted. The camshaft sensor works with the crankshaft position sensor and is essential to determining the fuel injection timing on each engine cylinder.

This is actually an easy swap out. Remove the electrical connection, remove the retaining bolt and pull out old one. I believe the sensor is located in the front passenger side of the engine on this particular model.
