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 MAP sensor.

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

1. Disconnect the negative battery cable.
2. Remove the engine cover. Refer to Engine Cover Replacement in Interior Trim.



3. Disconnect the MAP sensor harness connector.

Notice: Do not rotate or pry on the MAP sensor when removing. Damage to the MAP sensor or the intake manifold may result.





Important: If the original MAP sensor is to be reused after removing the MAP sensor from the intake manifold, replace the MAP sensor to intake manifold grommet.

4. Remove the MAP sensor by pulling straight up with a slight rocking motion.
5. Remove and discard the MAP sensor grommet.

1. Install the new MAP sensor grommet on the MAP sensor.
2. Install the MAP sensor.



3. Connect the MAP sensor harness connector.
4. Reinstall the engine cover. Refer to Engine Cover Replacement in Interior Trim.
5. Connect the negative battery cable.
