Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Proceed to 

EC-485, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000011278201

1.

CHECK REFRIGERANT PRESSURE SENSOR POWER SUPPLY

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 3.

NO

>> GO TO 2.

2.

CHECK REFRIGERANT PRESSURE SENSOR POWER SUPPLY CIRCUIT

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.

Is the inspection result normal?

YES

>> Perform the trouble diagnosis for power supply circuit.

NO

>> Repair or replace error-detected parts.

3.

CHECK REFRIGERANT PRESSURE SENSOR GROUND CIRCUIT

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.

4. Also check harness for short to power.
Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace error-detected parts.

4.

CHECK REFRIGERANT PRESSURE SENSOR INPUT SIGNAL CIRCUIT

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

tor.

2. Also check harness for short to ground and to power.
Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Repair or replace error-detected parts.

5.

CHECK INTERMITTENT INCIDENT

Check intermittent incident. Refer to 

GI-44, "Intermittent Incident"

.

Is the inspection result normal?

YES

>> Replace refrigerant pressure sensor. Refer to 

HAC-108, "Removal and Installation"

 (with auto-

matic air conditioner) or 

HAC-184, "Removal and Installation"

 (with manual air conditioner).

NO

>> Repair or replace error-detected parts.

SENSOR POWER SUPPLY2 CIRCUIT

Description

INFOID:0000000011278202

ECM supplies a voltage of 5 V to some of the sensors systematically divided into 2 groups, respectively.

Accordingly, when a short circuit develops in a sensor power source, a malfunction may occur simultaneously

in the sensors belonging to the same group as the short-circuited sensor.

Sensor power supply 1

• APP sensor 1

• CKP sensor (POS)

• Intake manifold runner control valve position sensor

• Refrigerant pressure sensor

• TP sensor

NOTE:

If sensor power supply 1 circuit is malfunctioning, DTC P0643 is displayed.

Sensor power supply 2

• APP sensor 2

• CMP sensor (PHASE)

• EVT control position sensor

• EOP sensor

• MAF sensor

Diagnosis Procedure

INFOID:0000000011278203

1.

CHECK APP SENSOR 2 POWER SUPPLY CIRCUIT-1

1. Turn ignition switch OFF.

2. Disconnect accelerator pedal position (APP) sensor harness connector.

3. Turn ignition switch ON.

4. Check the voltage between APP sensor harness connector and ground.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> GO TO 2.

2.

CHECK APP SENSOR 2 POWER SUPPLY CIRCUIT-2

1. Turn ignition switch OFF.

2. Disconnect ECM harness connector.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair open circuit.

3.

CHECK SENSOR POWER SUPPLY 2 CIRCUIT

1. Disconnect following sensors harness connector.

2. Check harness for short to power and short to ground, between the following terminals.
