    What is this sensor? And what does it do? It's on Michelle's new truck, 1996 Z71 with a 5.7 and is located on the passenger side of the engine block between the starter and motor mount.
    Thanks

    knok sensor. AND IT retards the timing if pinging in motor from predetination. you need it to run stock fuel injection. or you can get aftermarket chip and run with out. best to leave it in.

    Thats interesting that they used this same location for the knock sensor on the truck as they did for my electric fan sensor on my '88 Iroc Camaro. :thinking:

    Its into the water jacket so it would pull temp. Personnaly I think thats a bad location for a temp sensor. Thats right at the bottom of the water jackets and its very common to get sediment down there. If that happend then it might throw off the temp the fan comes on at.

    You sure thats not the knock sensor on yours as well? Coolant temp sensors are ususally into the heads where the highest temps are and where it heats first. Vary little heat is generated down that low on the block. Its at the bottom of the stroke.

    The TPI and TBI Camaros had their knock sensor in the same position. The fan temp switch was installed in the head where our trucks have the temp sender for the gauge.
