Where is a crankshaft sensor on a 1997 Chevrolet Lumina and what does it look like?
Hidden behind the harmonic balancer. You will need a puller to remove the balancer. It will be black, a couple of inches long, with a wire coming out of it. The frame of it is usually aluminum, and adjustable. You will need an alignment tool to adjust the sensor.
WOW WAY TO NAME ALL OF THEM LOL it is the crankshaft position sensor and either knocks sensor or camshaft position sensor First off if you a have a 3.1 it is the KNock Sensor. Crankshaft sensor and cam sensor is on the belt side of the motor. Crank is on bottom behind the big pully and cam is on top(half way up) usually under power steering pump
