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 ECM harness connector and refrigerant pressure sensor 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.

Perform 

GI-45, "Intermittent Incident"

.

Is the inspection result normal?

YES

>> Replace refrigerant pressure sensor. Refer to 

HA-36, "Exploded View"

.

NO

>> Repair or replace error-detected parts.

SENSOR POWER SUPPLY 2 CIRCUIT

SENSOR POWER SUPPLY 2 CIRCUIT

Description

INFOID:0000000012198770

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

• Crankshaft position sensor

• Battery current sensor

• EGR pressure sensor

• Intake manifold runner control valve position sensor

• Manifold absolute pressure sensor

• EGR volume control valve

• Electric wastegate position sensor

• Multi-way control valve position sensor

• Exhaust valve timing control position sensor

• Throttle position sensor

• Accelerator pedal position sensor 1

NOTE:

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

Sensor power supply 2

• Mass air flow sensor

• G sensor

• Refrigerant pressure sensor

• Fuel rail pressure sensor

• Engine oil pressure sensor

• Turbocharger boost sensor

• Camshaft position sensor

• Accelerator pedal position sensor 2

Diagnosis Procedure

INFOID:0000000012198771

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 1 POWER SUPPLY CIRCUIT-2

1. Turn ignition switch OFF.

2. Disconnect ECM harness connector.

3. Check the continuity between APP sensor harness connector and ECM harness connector.

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.

Is the inspection result normal?

YES

>> GO TO 4.

NO

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

4.

CHECK COMPONENTS

Check the following.

• APP sensor 2 (Refer to 

EC-1146, "Component Inspection"

.)

• FRP sensor (Refer to 

EC-921, "Component Inspection"

.)

• EOP sensor (Refer to 

EC-1040, "Component Inspection"

.)

• Turbocharger boost sensor (Refer to 

EC-939, "Component Inspection"

.)

• Camshaft position sensor (PHASE) (Refer to 

EC-954, "Component Inspection"

.)

• Mass air flow sensor (Refer to 

EC-845, "Component Inspection"

.)

• Refrigerant pressure sensor (Refer to 

EC-1238, "Diagnosis Procedure"

.)

• G sensor (Refer to 

EC-1122, "Component Inspection"

.)

Is the inspection result normal?

YES

>> Perform 

GI-45, "Intermittent Incident"

.

NO

>> Replace malfunctioning component.
