REFRIGERANT PRESSURE SENSOR
2007 Versa
REFRIGERANT PRESSURE SENSORPFP:92136
Component DescriptionUBS00PU5
The refrigerant pressure sensor (1) 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.
