Where is crankshaft ignition sensor on 1996 Buick Roadmaster?

The crankshaft position sensor (CKP) on a 1996 Buick Roadmaster is located on the passenger side of the engine block, near the transmission bellhousing. It's usually mounted in a fairly accessible location, but you'll need to look closely near the bottom of the engine, towards the front.

To be more precise, you'll likely find it somewhere near the area where the crankshaft and transmission meet.

Because exact location can vary slightly depending on the specific engine (LT1 or L99), it's best to:

1. Consult a repair manual: A Haynes or Chilton manual specific to your 1996 Buick Roadmaster will have diagrams and precise instructions. This is the most reliable method.

2. Use an online repair database: Websites like AllDataDIY or Mitchell 1 (subscription required) provide detailed diagrams and procedures for different vehicle models.

Caution: Working on the engine requires some mechanical aptitude. If you're not comfortable working on cars, it's advisable to take it to a qualified mechanic. Misplacing or damaging other components while searching for the sensor is possible.
