How do you replace the crank position sensor on a 1992 Pontiac Grand Prix?

You must replace the crankshaft sensor very carefully. There is

a small bolt that holds it in place on the back side of the

engine,(usually an 8mm socket does the trick)you can access that

bolt by reaching under the car between the transmission and the

engine. when that bolt is out you must twist and pull the sensor at

the same time. If you have a problem getting it out you can use a

screwdriver to start to pry it out but becareful not to break it.

If you break it and it is still in the engine block you will need

to drop the oil pan and pound it out from the bottom.

I may sound crazy, but i had an easier time with the sensor

after i removed the coolant tank, the alternator and the alternator

mounting bracket. You will get an almost straight shot from above

especially if you jack the engine up a few inches. Though it is

best to spot its position from the bottom so you know where to put

your hand.
