Removal Procedure

WARNING: This page is about a different car, the 2004 GMC Safari and 2004 Chevrolet Astro. However, it is still accessible from the selected car via links, so may be relevant.

Other than checking for a worn grommet and loose electrical connectors, the only service possible is a unit replacement if the diagnosis shows a malfunctioning manifold absolute pressure (MAP) sensor.

Turn OFF the ignition.
Remove the engine cover. Refer to Engine Cover Replacement in Interior Trim.
Disconnect the MAP sensor harness connector.

Remove the MAP sensor by pulling straight up with a slight rocking motion.
