This video shows you how to install a new (intake/exhaust) camshaft position sensor in your 2002-2009 Chevrolet Trailblazer (4.2L L6). For vehicles with electronically controlled timing, a camshaft position sensor relays important information to the computer to ensure the engine is running properly. A bad sensor may relay incorrect or no information, resulting in poor running conditions and trouble codes.

This repair was done on a 2007 Chevrolet Trailblazer LT 4.2L Sport Utility 4-Door 4WD Automatic and the process should be similar on the following vehicles:
2002 Chevrolet Trailblazer
2003 Chevrolet Trailblazer
2004 Chevrolet Trailblazer
2005 Chevrolet Trailblazer
2006 Chevrolet Trailblazer
2007 Chevrolet Trailblazer
2008 Chevrolet Trailblazer
2009 Chevrolet Trailblazer

Tools you will need:
