The crankshaft position sensor should be located behind the vibration damper/harmonic balancer and it will have to be removed before the crankshaft position sensor can be replaced. (Let me know if you require assistance with the proceedure)

Also, it usually requires a special tool to align that sensor (available from most auto part stores) and if the sensor is not properly aligned then damage to the sensor or the tone ring can occur.

Here is an image of the crankshaft position sensor with the vibration damper/harmonic balancer removed.

How do i replace a crank shaft sensor on a 2001 buick lesabre


The crankshaft sensor is located behind the harmonic balancer. There is a special tool you can rent/loan from your local auto parts store in order to remove the harmonic balancer. Once it is off 2 bolt hold the crankshaft position sensor in place. Note there could be many other factors causing your engine to stall or not restart; but those crank sensors do tend to go out on those engines.

My engine stalls?


The crank sensor is located behind the crank pulley on the 3.8 liter. The crank pulley must first be removed. A 15/16" socket, three very long 8 x 1.0 bolts (pretty sure that is the size, some large washers, and a crank pulley pulley will be required.

With the crank pulley removed mark the bracket where the old crank sensor is located so that the new sensor can be placed in exactly the same position. Failure to do this will result in the new sensor and/or the crank pulley being severely damaged.

Then it's as simple as removing the old sensors and installing the new one.

Good luck and let me know if you have any questions.

You may need a shop manual to get the testing procedures. You need to know if the ignition module is getting power and a signal from the cam and crank sensors.
