Component Description
EBS00R3Y
The refrigerant pressure sensor is installed at the liquid tank 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.

Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
Diagnostic Procedure
EBS00R40
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 switch “ON”.
3.
Check voltage between ECM terminal 69 and ground with CON-
SULT-II or tester.
