Where is the crankshaft sensor located on a 1990 Jeep Wrangler 6 cylinder?

On a 1990 Jeep Wrangler with a 6-cylinder engine (likely a 4.2L), the crankshaft position sensor (CKP sensor) is typically located on the passenger side of the engine block, near the bellhousing. It's often mounted on the block itself, close to where the crankshaft's end meets the transmission.

However, precise location can vary slightly depending on the exact engine configuration. It's best to consult a repair manual specific to your 1990 Jeep Wrangler's 4.2L engine. A repair manual will have diagrams and clear explanations. You can also search online for images of a 1990 Jeep Wrangler 4.2L engine bay to get a visual reference.
