Nissan Rogue Service Manual: Sensor power supply2 circuit
Description
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
Diagnosis Procedure
1.CHECK APP SENSOR 2 POWER SUPPLY CIRCUIT-1
- Turn ignition switch OFF.
- Disconnect accelerator pedal position (APP) sensor harness connector.
- Turn ignition switch ON.
- Check the voltage between APP sensor harness connector and ground.
Is the inspection result normal? YES >> INSPECTION END
NO >> GO TO 2.
2.CHECK APP SENSOR 2 POWER SUPPLY CIRCUIT-2
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Check the continuity between APP sensor harness connector and ECM harness connector.
Is the inspection result normal? YES >> GO TO 3.
NO >> Repair open circuit.
3.CHECK SENSOR POWER SUPPLY 2 CIRCUIT
- Disconnect following sensors harness connector.
- 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.
- APP sensor 2 (Refer to EC-444, "Component Inspection".)
- Camshaft position sensor (PHASE) (Refer to EC-300, "Component Inspection (Camshaft position sensor)".)
- EVT control position sensor (Refer to EC-387, "Component Inspection".)
- EOP sensor (Refer toEC-360, "Component Inspection".)
- MAF sensor (Refer to EC-200, "Component Inspection".)
Is the inspection result normal? YES >> Refer to GI-41, "Intermittent Incident".
NO >> Replace malfunctioning component.
Refrigerant pressure sensor

Starting the engine (models without NISSAN
Intelligent Key® system)
Apply the parking brake.
Move the shift lever to P (Park) or N (Neutral).
P (Park) is recommended.
The shift lever cannot be moved out of
P (Park) and into any of the other gear
positions if the ignition key is turned to
the OFF position or if the key is removed

DTC Description
DTC DETECTION LOGIC
NOTE:
This self-diagnosis has the one trip detection logic. When malfunction A is
detected, DTC is not stored
in ECM memory. And in that case, 1st trip DTC and 1st trip freeze frame data are
displayed. 1st trip
DTC is erased when ignition switch OFF. And ...
