REFRIGERANT PRESSURE SENSOR
REFRIGERANT PRESSURE SENSOR
DescriptionINFOID:0000000001693449
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.
Component Function CheckINFOID:0000000001693450
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 fan switch ON.
3. Check the voltage between ECM harness connector terminals as follows.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Go to EC-632, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000001693451
1.CHECK GROUND CONNECTION
1. Turn A/C switch and blower fan switch OFF.
2. Stop engine.
3. Turn ignition switch OFF.
4. Check ground connection E15. Refer to Ground Inspection in GI-58, "
Circuit Inspection".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace ground connection.
2.CHECK REFRIGERANT PRESSURE SENSOR POWER SUPPLY CIRCUIT
1. Disconnect refrigerant pressure sensor harness connector.
2. Turn ignition switch ON.
3. Check the voltage between refrigerant pressure sensor harness connector and ground.
Is the inspection result normal?
YES >> GO TO 4.
NO >> GO TO 3.

DescriptionINFOID:0000000001697511
The vehicle speed signal is sent to the combination meter from the “ABS actuator and electric unit (control
unit)” by CAN communication line. The combination meter then sends a signal to the ECM by CAN communi-
cation line.

VALUES ON THE DIAGNOSIS TOOL
Remarks:
 Specification data are reference values.
 Specification data are output/input values which are detected or supplied by the ECM at the connector.
*Specification data may not be directly related to their components signals/values/operations.
I.e. Adjust ignition timing with a timing light before monitoring IGN TIMING, because the monitor may show the
specification data in spite of the ignition timing not being adjusted to the specification data. this IGN TIMING
monitors the data calculated by the ECM according to the signals input from the camshaft position sensor and
other ignition timing related sensors.
Monitor Item Condition Values/Status
ENG SPEED  Run engine and compare CONSULT-III value with the tachometer indication.Almost the same speed as
the tachometer indication.

ECM
*: Accelerator pedal position sensor 2 signal and throttle position sensor 2 signal are converted by ECM internally. Thus, they differ from
ECM terminals voltage signal.
TERMINAL LAYOUT
PHYSICAL VALUES
NOTE:
 ECM is located in the engine room left side near battery.
 Specification data are reference values and are measured between each terminal and ground.
 Pulse signal is measured by CONSULT-III.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECMs transistor. Use a ground other than ECM terminals, such as the ground.
