Where is the crankshaft positioning sensor located on a '92 buick century w/a 3.3 ci & how do you replace it.

Two crankshaft position sensors .
Crankshaft Position (CKP) Sensor (7X)
Lower rear of the engine block, below the exhaust manifold

Crankshaft Position (CKP) Sensor (24X)
Right side of the engine, at the end of the crankshaft, behind the harmonic balancer

Which one ? your vehicle has two !
Crankshaft Position (CKP) Sensor (7X)
Lower rear of the engine block, below the exhaust manifold
Crankshaft Position (CKP) Sensor (24X)
Right side of engine, at the end of the crankshaft, behind the harmonic balancer
24x replacement .
Turn OFF the ignition. Remove the serpentine drive belt from crankshaft pulley. Refer to Drive Belt Replacement in Engine Mechanical. Raise the vehicle on hoist. Refer to Lifting and Jacking the Vehicle in general information. Remove the crankshaft harmonic balancer. Refer to Crankshaft Balancer Replacement in Engine Mechanical. Note the routing of sensor harness before removal. Remove the harness retaining clip with bolt (1). Disconnect the sensor electrical connector. Remove the sensor bolts (2). Remove the sensor.
After replacement of this one you have to do relearn
24x 24

There are two crankshaft sensors on this engine. One is hidden behind the harmonic balancer, and the other is in the side of the block. Here are pictures of the each sensor and where they are.

Thanks.

A cheap cooling sensor might not start the fan. Make sure the one you or your mechanic bought is a quality product.

1. Crawl under the front of the vehicle and look up at the back side of the engine. The crankshaft position sensor is made from black plastic and has a two-wire connector attached to it. The sensor is located on the back side of the engine block, halfway between the oil pan and the top of the block.
   

have a great holiday !! they only use one sensor, a 3x or 24x. above is for 3x sensor, to replace 24x just call an auto parts store and they should tell you the location and how to change it.

Try a crank sensor. It's next to the crankshaft pulley and the pulley has to come off to replace. Special tools required.

did u test the fuel pressure before u installed the pump? it is more likely the crankshaft position sensor on the engine is defective, run a trouble code test and see if u have any codes for thei sensor. Go to this web site to read how to run a trouble code test.

Hello, the camshaft location on a 3.1 is located under the power steering pump. The crankshaft position sensor is on the back of the block above the transmission, middleways of the motor.
