Manifold Differential Pressure (MDP) Sensor - VITARA & Grand VITARA

Remove MDP sensor from intake manifold. Inspect intake manifold vacuum passage, MDP sensor air vent hole and vacuum passage for clogs. Clean passages if necessary. Inspect sensor O-ring for damage and deterioration.
See Figure for MDP sensor testing procedure. See MDP SENSOR OUTPUT VOLTAGE (OFF-VEHICLE) - VITARA & GRAND VITARA table for voltage specifications. If voltage readings are not within specifications, replace MDP sensor and retest system.
