Magnet Clutch Circuit
Magnet Clutch CircuitSYMPTOM: Magnet clutch does not engage.
INSPECTION FLOW
SYSTEM DESCRIPTION
Front air control controls compressor operation by ambient temperature and signal from ECM.
Low Temperature Protection Control
Front air control will turn the compressor ON or OFF as determined by a signal detected by ambient sensor.
When ambient temperature is greater than -2 °C (28 °F), the compressor turns ON. The compressor turns OFF when ambient temperature is less than -5 °C (23 °F).

COMPONENT INSPECTION
Refrigerant Pressure Sensor
The refrigerant pressure sensor is attached to the condenser.
- Refer to "Refrigerant pressure sensor".
- Make sure that the A/C refrigerant pressure and the sensor output voltage are within the specified range as shown in the A/C operating condition figure.
