P0643 SENSOR POWER SUPPLY
P0643 SENSOR POWER SUPPLY
Description
INFOID:0000000012198575
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
