Where is crank sensor located on GMC truck?

The location of the crankshaft position sensor (CKP sensor) on a GMC truck varies depending on the year, model, and engine. There's no single answer.

To find it, you'll need to:

1. Consult your vehicle's repair manual: This is the most reliable source. The manual will have diagrams showing the exact location of the sensor for your specific truck.

2. Use an online repair database: Sites like AllDataDIY or Chilton repair provide diagrams and information for many vehicles, often including CKP sensor location. You'll need your truck's year, make, model, and engine details.

3. Search online forums: Search for your specific GMC truck model and year along with "crankshaft position sensor location." Other owners may have posted photos or descriptions.

General Locations (but not guaranteed for your truck): The CKP sensor is typically found near the crankshaft pulley, often on the engine block itself, sometimes on the transmission bellhousing. It's usually in a somewhat easily accessible area, but the exact location varies widely.

Important Note: Before attempting any work on your vehicle, disconnect the negative battery terminal to prevent accidental short circuits. If you're unsure about working on your vehicle's engine, take it to a qualified mechanic.
