Toyota RAV4 (XA40) 2013-2018 Service Manual: Compressor lock sensor circuit
Description
This sensor sends 1 pulse per engine revolution to the air conditioning amplifier. If the ratio of the compressor speed divided by the engine speed is smaller than a predetermined value, the air conditioning amplifier turns the compressor off, and the indicator blinks at approximately 1 second intervals.
