This is the new replacement Vane Position Sensor for the 2004.5 to 2011 LLY, LBZ, & LMM Duramax. The same sensor works for all the Duramax motors from LLY, LBZ, LMM 6.6 Liter Motors from 2004.5 on up to 2011. What is required to facilitate this is the adapter you see that comes with the VPS. The adapter is Model and year specific. If you have an LLY: you will use the adapter harness pictured. If you have the LBZ & LMM you do not utilize the harness adapter pictured, you just plug directly into the pickups wiring harness.
