Manifold Differential Pressure Sensor - Esteem (1.8L), Grand VITARA, VITARA & XL-7
- Remove Manifold Differential Pressure (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) - ESTEEM (1.8L), VITARA, GRAND VITARA & XL-7
table for voltage specifications. If voltage readings are not within specifications, replace MDP sensor and retest system.
