Where is camshaft position sensor located on a 03 Saturn vue 4-cylinder?

On a 2003 Saturn Vue 4-cylinder, the camshaft position sensor (CMP sensor) is typically located on the front of the engine, near the timing chain cover. It's usually positioned directly above or near the camshaft sprocket.

However, without a specific diagram for your exact engine (different variations exist, even within the same year), this is the most general location. Consult a repair manual specific to your vehicle's engine code (often found on a sticker under the hood or in the owner's manual) for a precise location. A visual inspection with the help of a diagram from a reputable source (like a Haynes or Chilton repair manual) is the best way to be sure.
