REFRIGERANT PRESSURE SENSOR
REFRIGERANT PRESSURE SENSOR
DescriptionINFOID:0000000005398631
The refrigerant pressure sensor is installed at the condenser of the air conditioner system. The sensor uses an
electrostatic volume pressure transducer to convert refrigerant pressure to voltage. The voltage signal is sent
to ECM, and ECM controls cooling fan system.
Component Function CheckINFOID:0000000005398632
1.CHECK REFRIGERANT PRESSURE SENSOR OVERALL FUNCTION
1. Start engine and warm it up to normal operating temperature.
2. Turn A/C switch and blower fan switch ON.
3. Check the voltage between ECM harness connector and ground.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Go to EC-451, "
Diagnosis Procedure".
