REFRIGERANT PRESSURE SENSOR
Component DescriptionINFOID:0000000001326460
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.

Wiring Diagram
INFOID:0000000001326461
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring in put/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground ot her than ECM terminals, such as the ground.
