Nissan Juke Service and Repair Manual : P0850 PNP switch

Description

For CVT models, transmission range switch is turn ON when the selector lever is P or N.

For M/T models, park/neutral position (PNP) range switch is ON when the selector lever is Neutral position.

ECM detects the position because the continuity of the line (the ON) exists.

DTC CONFIRMATION PROCEDURE


DTC CONFIRMATION PROCEDURE

1.INSPECTION START

Do you have CONSULT-III? Do you have CONSULT-III? YES >> GO TO 2.

NO >> GO TO 5.

2.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.

>> GO TO 3.

3.CHECK PNP SIGNAL FUNCTION

1. Turn ignition switch ON.With CONSULT-III


1. Turn ignition switch ON.

2. Select “P/N POSI SW” in “DATA MONITOR” mode of “ENGINE” using CONSULT-III. Then check the “P/N POSI SW” signal as per the following conditions.

Is the inspection result normal?


Is the inspection result normal? YES >> GO TO 4.

NO >> Proceed to EC-310, "Diagnosis Procedure".

4.PERFORM DTC CONFIRMATION PROCEDURE

1. Select “DATA MONITOR” mode of “ENGINE” using CONSULT-III.

2. Start engine and warm it up to normal operating temperature.

3. Maintain the following conditions for at least 60 consecutive seconds.

CAUTION:
Always drive vehicle at a safe speed.

4. Check 1st trip DTC.


4. Check 1st trip DTC.

Is 1st trip DTC detected? YES >> Proceed to EC-310, "Diagnosis Procedure".

NO >> INSPECTION END 5.PERFORM COMPONENT FUNCTION CHECK

Perform component function check. Refer to EC-310, "Component Function Check".

NOTE

:
Use component function check the overall function of the transmission range switch circuit (CVT models) or the park/neutral position (PNP) switch circuit (M/T models). During this check, a 1st trip DTC might not be confirmed.

Is the inspection result normal? YES >> INSPECTION END

NO >> Proceed to EC-310, "Diagnosis Procedure".

Component Function Check

1.PERFORM COMPONENT FUNCTION CHECK

1. Turn ignition switch ON.

2. Check the voltage between ECM harness connector and ground as per the following conditions.

Is the inspection result normal?


Is the inspection result normal? YES >> INSPECTION END

NO >> Repair or replace error-detected parts.

4.CHECK TRANSMISSION RANGE SWITCH SIGNAL CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect ECM harness connector.

3. Check the continuity between transmission range switch harness connector and ECM harness connector.

4. Also check harness for short to ground and to power.


4. Also check harness for short to ground and to power.

Is the inspection result normal? YES >> GO TO 5.

NO >> Repair or replace error-detected parts.

5.CHECK TRANSMISSION RANGE SWITCH

Check the transmission range switch. Refer to TM-201, "Component Inspection".

Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".

NO >> Replace transmission range switch. Refer to TM-278, "Removal and Installation".

6.CHECK PARK/NEUTRAL POSITION (PNP) SWITCH POWER SUPPLY

1. Turn ignition switch OFF.

2. Disconnect PNP switch harness connector.

3. Turn ignition switch ON.

4. Check the voltage between PNP switch harness connector and ground.

Is the inspection result normal?


Is the inspection result normal? YES >> GO TO 7.

NO >> Perform the trouble diagnosis for power supply circuit.

7.CHECK PNP SWITCH INPUT SIGNAL CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect ECM harness connector.

3. Check the continuity between PNP switch harness connector and ECM harness connector.

4. Also check harness for short to ground and to power.


4. Also check harness for short to ground and to power.

Is the inspection result normal? YES >> GO TO 5.

NO >> Repair or replace error-detected parts.

8.CHECK PNP SWITCH

Check the PNP switch. Refer to TM-73, "PARK/NEUTRAL POSITION (PNP) SWITCH : Component Inspection".

Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".

NO >> Replace PNP switch. Refer to TM-77, "Removal and Installation".
