Under the fuel injector rail just above the oil pan. You can only see it if you are under the car looking at the oil filter. The sensor is 25 cm to your left next to the oil pressure sensor.
Rear of the engine block.
It is located on the back side of the engine, where the distributor originally went.
The crankshaft position sensor is located behind the starter on the front of the engine. Hope this helps! Mitch art_y2k1@yahoo.com
On the firewall side of the engine block, near the transmission bellhousing, under the intake manifold that answer sir, is incorrect, the cavaliers did not use a cam sensor, only a crank sensor, but the location is right for the crank sensor
what size engine 2.2
In the back by the coil pack.
The crank sensor is located on the back engine wall in the middle, just under the two coil packs (from where the spark plug wires come). There is a wire harness from the crank sensor to the module which holds the two coil pack. The crank sensor is held into the engine by a single bolt. To see all of this, you have to go under the car. I am having an intermittent no start problem with my 93 Cavalier (it cranks, but no spark at all) and I think the crank sensor is my problem.
Its on the backside of the engine, on the firewall side
Hey Jeff== It depends on which engine you have but I imagine it is on the module and senses notches on the crankshaft. GoodluckJoe
Problem with the signal from the Crank Sensor.
its at back of engne just under the manifold
if the crank sensor is bad it does not tell the computer that the crank is turning it will not fire up the engine.
