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
