Locate crank sensor on 1990 buick century


Hello, the crank position sensor or (CPS) censor is located directly behind the harmonic balancer (or fly wheel at the very bottom). The sensor is located on the right side of the harmonic balancer when facing the front of the motor. You must remove the harmonic balancer to replace the sensor. You must also re-align the sensor with 30 thousands of an inch tolorence, or your car may idle rough or may not start. I own a 1990 Buick Century and just replaced my CPS sensor last month. There is a trick I learned to reinstalling the new sensor. Let me know if you need that information.
