P0643 SENSOR POWER SUPPLY

P0643 SENSOR POWER SUPPLY

Description

INFOID:0000000011278098

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

• 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

DTC Description

INFOID:0000000011278099

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connectors

- APP sensor 1 circuit is shorted.

- CKP sensor (POS) circuit is shorted.

- Intake manifold runner control valve position sensor circuit is shorted.

- TP sensor circuit is shorted.

- Refrigerant pressure sensor circuit is shorted.

• Accelerator pedal position sensor

• CKP sensor (POS)

• Intake manifold runner control valve position sensor

• Throttle position sensor

• Refrigerant pressure sensor

FAIL-SAFE

ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (approx.

5 degrees) by the return spring.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure

before conducting the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

TESTING CONDITION:

Before performing the following procedure, confirm that battery voltage is more than 10 V at idle.

DTC No.

Diagnosis Procedure

INFOID:0000000011278100

1.

CHECK GROUND CONNECTION

1. Turn ignition switch OFF.

2. Check ground connection E9 and E15. Refer to Ground Inspection in 

GI-46, "Circuit Inspection"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace ground connection.

2.

CHECK ACCELERATOR PEDAL POSITION SENSOR 1 POWER SUPPLY CIRCUIT

1. Disconnect accelerator pedal position (APP) sensor harness connector.

2. Turn ignition switch ON.

3. Check the voltage between APP sensor harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> GO TO 3.

3.

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 4.

NO

>> Repair short to ground or short to power in harness or connectors.

4.

CHECK COMPONENTS

Check the following.

• Crankshaft position sensor (POS) (Refer to 

EC-300, "Component Inspection (Crankshaft Position sensor)"

.)

• Intake manifold runner control valve position sensor (Refer to 

EC-427, "Diagnosis Procedure"

.)

• Refrigerant pressure sensor (Refer to 

EC-485, "Diagnosis Procedure"

.)

• TP sensor (Refer to 

EC-221, "Component Inspection"

.)

Is the inspection result normal?

YES

>> GO TO 5.
