REFRIGERANT PRESSURE SENSOR
Component Description INFOID:0000000004537540
The refrigerant pressure sensor (1) is installed at the condenser of
the air conditioner system. The sens or 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.

REFRIGERANT PRESSURE SENSOR
Wiring Diagram INFOID:0000000004537541
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. BBWA2662E
