SENSOR POWER SUPPLY 2 CIRCUIT
DescriptionINFOID:0000000009462458
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
• Battery current sensor
• 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 ProcedureINFOID:0000000009462459
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
