P1706 PNP SWITCH

P1706 PNP SWITCH

Description

INFOID:0000000001161922

When the shift lever position is Neutral position, park/neutral position (PNP) switch is ON.
ECM detects the position because the continuity of the line (the ON signal) exists.

Check 1st trip DTC.

Is 1st trip DTC detected?

YES

>> Go to 

EC-943, "Diagnosis Procedure"

.

NO

>> INSPECTION END

5.

PERFORM COMPONENT FUNCTION CHECK

Perform component function check. Refer to 

EC-943, "Component Function Check"

.

NOTE:
Use component function check the overall function of the park/neutral position (PNP) switch circuit. During this
check, a 1st trip DTC might not be confirmed.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Go to 

EC-943, "Diagnosis Procedure"

.

Component Function Check

INFOID:0000000001161924

1.

PERFORM COMPONENT FUNCTION CHECK

1.

Turn ignition switch ON.

2.

Check the voltage between ECM harness connector terminal as follows.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Go to 

EC-943, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000001161925

1.

CHECK PNP SWITCH POWER SUPPLY CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect Park/neutral position (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?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

DTECTED MALFUNCTIONING PART

Check the following.
• Harness connectors E8, F8
• Harness for open or short between PNP switch and IPDM E/R

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

3.

CHECK PNP SWITCH INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

1.

Turn ignition switch OFF.
