Part# 12575182-Update - Camshaft Position Sensor Update Kit for 2001-2003 GM 8.1L
This is a packaged kit that contains all the necessary components to convert your GM 8.1L to the newer style camshaft position sensor (12591720) that is readily available. The stock engine computer will run this new setup without any issues, so no tuning or updates are required.
The 2001 camshaft gear / sprocket and camshaft timing position sensor were revised in 2002 and again in 2004 to maximize the benefits of Magnetic Relutance (MR) or "mirror image" ignition timing. To "read" the new changes, the camshaft position sensor also had to be updated to match the 2004+ camshaft gear. The older style camshaft position sensor (12575182) was discontinued by GM and is only available in limited quantities.
