Description
ECM supplies a voltage of 5.0 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 shorted-circuit sensor.
Sensor power supply 1
NOTE:
If sensor power supply 1 circuit is malfunctioning, DTC P0643 is displayed.
Sensor power supply 2
DTC Logic
DTC DETECTION LOGIC
DTC No. | CONSULT screen terms (Trouble diagnosis content) | DTC detecting condition | Possible cause |
P0643 | SENSOR POWER/CIRC (Sensor reference voltage ″A″ circuit high) | ECM detects that the voltage of sensor power supply 1 is excessively low or high. |

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10 V at idle.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDUR
Is DTC detected? YES >> Refer to EC-354, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK ACCELERATOR PEDAL POSITION SENSOR 1 POWER SUPPLY CIRCUIT
Is the inspection result normal? YES >> GO TO 4.
NO >> GO TO 2.
2.CHECK SENSOR POWER SUPPLY CIRCUITS
Check harness for short to power and short to ground, between the following terminals.
Is the inspection result normal? YES >> GO TO 3.
NO >> Repair short to ground or short to power in harness or connectors.
3.CHECK COMPONENTS
Check the following.
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace malfunctioning component.
4.CHECK APP SENSOR
Check APP sensor. Refer to EC-433, "Component Inspection (APP Sensor)".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace accelerator pedal assembly. Refer to ACC-3, "Removal and Installation".
