Where is the crank sensor on a gm 3.4?

On a GM 3.4L engine, the crankshaft position sensor is typically located near the bottom of the engine, mounted on the engine block or transmission bell housing. It is usually positioned close to the crankshaft pulley or flywheel. To access it, you may need to remove some components or shields, depending on the specific vehicle model. Always refer to a repair manual for precise location details and removal instructions.
