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.
