Where is the 2007 chevy silverado 5.3 camshaft position sensor located?

The camshaft position sensor on the 2007 Chevrolet Silverado'S5.3L engine is located on the left side (passenger's side) of the engine block, underneath the cover. While the swap itself is quite simple once You remove the retaining bolt, You'll need to tear down a good portion of the engine cover and hardware to it. If You're looking to replace the part, You can expect to pay around $35 to $55, depending on brand. If You're dealing with a mechanic, the cost becomes around $200 to $275, including parts and labor. The job is estimated to take a professional around 3 to 4 hours of labor, so most DIYers can expect to take an entire afternoon or longer to complete the swap.
