Compressor Speed Sensor: Testing and Inspection

CIRCUIT DESCRIPTION

This sensor sends 1 pulse par engine revolution to the ECM. If the number ratio of the compressor speed divided by the engine speed is smaller than a
predetermined value, the ECM turns the compressor off. And, the indicator flashes at about 1 second interval.
