Where is crank sensor for a 92 Pontiac Sunbird convertible with 3.1 engine?

The crank sensor on a 1992 Pontiac Sunbird convertible with a 3.1L engine is located on the passenger side of the engine block, near the rear (towards the firewall) of the engine. It's usually mounted on the engine block itself, and you'll likely see a single-wire connector attached to it. It's a relatively small sensor.

However, to be absolutely certain, you should:

* Consult a repair manual specific to your 1992 Pontiac Sunbird 3.1L: A Haynes or Chilton manual will have diagrams showing the exact location.

* Search online for images: Search for "1992 Pontiac Sunbird 3.1L crank sensor location" on Google Images. This can provide visual confirmation.

Remember to be careful when working around the engine. Disconnect the negative battery terminal before starting any work.
