Removal Height Sensor 1. Disconnect the negative (-) battery terminal. 2. Remove the height sensor linkage (A) installed on the front axle and rear axle. [Front] [Rear] Installation Height Sensor 1. Install the height sensor assembly after connecting the connector.
Description A/C pressure transducer convert the pressure value of high pressure line into voltage value after measure it. By converted voltage value, engine ECU controls cooling fan by operating it high speed or low speed. Engine ECU stop the operation of compressor when the temperature of refrigerant line is so high or so low irregularl
