Description

INFOID:0000000000956135

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.

P0530 REFRIGERANT PRESSURE SENSOR

P0530 REFRIGERANT PRESSURE SENSOR

Description

INFOID:0000000001115155

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.

NOTE:
• If DTC P0530 is displayed with DTC P0641, first perform the trouble diagnosis for DTC P0641 Refer to

EC-1393, "DTC Logic"

.

Diagnosis Procedure

INFOID:0000000000956142

1.

CHECK GROUND CONNECTIONS

1.

Turn ignition switch OFF.

2.

Check ground connection E17. Refer to Ground inspection in

GI-41, "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 connector and ground.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> GO TO 3.

3.

DETECT MALFUNCTIONING PART

Check the following.
• Harness connector E6, F123
• Harness for open or short between ECM and refrigerant pressure sensor

>> Repair open circuit or short to ground or short to power in harness or connectors.

4.

CHECK REFRIGERANT PRESSURE SENSOR GROUND CIRCUIT FOR OPEN AND SHORT

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connector.

3.

Check the continuity between refrigerant pressure sensor harness connector and ECM harness connec-
tor.

DTC No.
