What happens when you turn off 4WD on a Nissan?
The LOCK mode will automatically be cancelled when the ignition switch is turned to the “OFF” position. ● If the 4WD mode switch is operated while making a turn, accelerating or decelerating, or if the ignition switch is turned off while in the AUTO or LOCK mode, you may feel a jolt. This is normal.
Why does the 4WD warning light blink on and off?
If any malfunction occurs in the 4WD system when the ignition switch is in the “ON” position, the warning light will either remain illuminated or blink. High-temperature power train oil due to continuous operation of the vehicle to free a stuck vehicle makes the warning light blink rapidly (about twice per second).
How to know if you are in 4WD or 2WD?
A large difference between the diameters of front and rear wheels will make the warning light blink slowly (about once per 2 seconds). Pull off the road in a safe area, and idle the engine. Check that all tire sizes are the same, tire pressure is correct and tires are not worn. Change the 4WD mode switch to the 2WD mode and do not drive fast.

How does the TPS work on a Nissan Pathfinder?
In layman’s terms, this means that the TPS is tasked with the job of measuring how much you step on or step off the accelerator pedal as you’re driving the down the road. This throttle plate angle information is then sent to your Nissan’s fuel injection computer as a voltage DC signal. To give you a few more specifics:
