P1706 INFINITI, NISSAN: PARK AND NEUTRAL POSITION SWITCH
The gearshift lever is used to activate or deactivate, as required, the gearbox ratios. In the case of vehicles with a manual transmission, this lever is used to shift gears. This is an action that is usually carried out while the clutch is depressed to release the engine from the transmission and the wheels.
When the shift position is P or N, the park/neutral position switch is activated. The ECM (Engine Control Module) detects this position due to line continuity. The PNP (Park/Neutral Position) switch assembly also signals a transmission range switch, so it is possible to detect the position of the shift lever.
The diagnostic code P1706 OBDII is used by Infiniti and Nissan manufacturers to indicate that the park/neutral position switch signal does not change in the process of starting and driving the vehicle.
