P1706 PNP SWITCH

P1706 PNP SWITCH

Description

INFOID:0000000001094253

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

nal under the following conditions.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Go to

EC-1153, "Diagnosis Procedure"

.

4.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Select “DATA MONITOR” mode with CONSULT-III.

2.

Start engine and warm it up to normal operating temperature.

3.

Maintain the following conditions for at least 50 consecutive seconds.

CAUTION:

Always drive vehicle at a safe speed.
