Nissan Rogue (T33) 2021-Present Service Manual: P06b0 Sensor Power Supply 1

DTC Description

DESCRIPTION

ECM supplies a voltage of 5 V to some of the sensors systematically divided into 3 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

• Crankshaft position sensor

• Exhaust camshaft position sensor

• EGR volume control valve

• Throttle position sensor

• Fuel rail pressure sensor

• Mass air flow sensor

• ADM valve

• Electric wastegate control valve

• Multi-way control valve

• Turbocharger boost sensor

NOTE:

If sensor power supply 1 circuit is malfunctioning, DTC P06B0 is displayed.

Sensor power supply 2

• APP sensor 2

• Camshaft position sensor (PHASE)

• Crankshaft position sensor 2

• Refrigerant pressure sensor

• Crankcase pressure sensor

• Engine oil pressure sensor

• Manifold absolute pressure (MAP) sensor

• EGR differential pressure sensor

• Exhaust gas temperature sensor

Sensor power supply 3

• EVAP control system pressure sensor

  • Electric wastegate control valve position sensor is shorted.

  • Multi-way control valve position sensor is shorted.

  • Turbocharger boost sensor is shorted.

• CKP sensor

• Exhaust camshaft position sensor

• EGR volume control valve position sensor

• Throttle position sensor

• Fuel rail pressure sensor

• Mass air flow sensor

• Accelerator pedal position sensor 1

• ADM valve

• Electric wastegate control valve

• Multi-way control valve

• Turbocharger boost sensor

DTC CONFIRMATION PROCEDURE

PRECONDITIONING

TESTING CONDITION:

Before performing the following procedure, confirm that battery voltage is 11 V or more with ignition switch ON.

GO TO 2.

PERFORM DTC CONFIRMATION PROCEDURE

1. Turn ignition switch ON and wait at least 10 second.

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

3. Repeat step 1 and 2 for 2 times.

4. Turn ignition switch ON.

5. Check the DTC.

Is the DTC detected?

Proceed to DTC Diagnosis Procedure.

To check malfunction symptom before repair: Refer to Intermittent Incident.

Confirmation after repair: INSPECTION END

DTC Diagnosis Procedure

CHECK ECM POWER SUPPLY AND GROUND CIRCUIT

Perform trouble diagnosis for ECM power supply and ground circuit. Refer to Diagnosis Procedure.

Is the inspection result normal?

GO TO 2.

Repair or replace error-detected parts.

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.

   +		-	Voltage (Approx.)
   APP sensor
   Connector	Terminal
   E25	3	Ground	5 V

Is the inspection result normal?

GO TO 5.

GO TO 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?

GO TO 4.

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

CHECK COMPONENTS
