However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
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. Do not rotate or pry on the MAP sensor when removing. Damage to the MAP sensor or the intake manifold may result.
