INFOID:0000000011278200
1.
CHECK REFRIGERANT PRESSURE SENSOR 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 under the following conditions.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Proceed to
.
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.

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