Manifold Pressure/Vacuum Sensor: Service and Repair

    The MAP and Vacuum sensors are accessible through the engine compartment. The BARO sensor may be located either in the engine compartment or
strapped to the ECM harness under the dash panel.
    Other than checking for loose hoses and electrical connections, the only service required of these sensors is replacement, should diagnosis show any
sensors to be faulty.
