ZBN Camshaft Position Cam Sensor 12591720 Compatible with Chevy Express Silverado Suburban 1500 2500 Tahoe SSR Colorado GMC Savana Sierra Yukon Envoy Isuzu Saab Buick Pontiac

I saw it said GMC Envoy and ordered it only to find out it fits an 8 cylinder and not a 6 cylinder.

I was surprised at the value of this part it was a low cost purchase that fired the truck up on the firstattempt I ran the scanner on this and the count was right on the money.

This does not fit a 2006 Trailblazer 4.2L

Bought this for my 09 pontiac g8 only worked for a few miles and threw a CEL for a cam sensor performand code Replaced sensor from a auto parts store problem solved

Through a code 2 times I should have bought a ac delco oem for all the work
