Compressor Speed Sensor: Description and Operation
CIRCUIT DESCRIPTION
This sensor sends 4 pulses per 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 intervals.
