Manifold Absolute Pressure Sensor Replacement RPO L35

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. 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: After removing the MAP sensor from the intake manifold, replace the MAP sensor to the intake manifold grommet.

4. Discard the MAP sensor grommet.

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