P0530 REFRIGERANT PRESSURE SENSOR

P0530 REFRIGERANT PRESSURE SENSOR

Description

INFOID:0000000001162634

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.
