The 2.4 liter, 3.0L and 3.3L engines that year all use a Manifold Absolute Pressure Sensor (MAP) which is not cleanable. To test it an oscilloscope is used to moniter and look at smooth voltage change as the throttle is increased/air entering the engine is increased. A better scan tool can read the volume of air entering the engine in grames per second and give a voltage change reading or the sensor as the van is driven.
