Question about 2002 GMC Envoy
Hi, the crank sensor is located on the drivers side rear of engine just below the starter.
Very easy to replace.
Once you replace the sensor and start the truck the check engine light is going to illuminate. You must preform a crankshaft variation learn. unfortunately, you need a scan tool to preform this task.
