How odd! Your Nissan NV200’s tire pressure monitoring system (TPMS) light should turn off automatically after you correct your tire pressure to the appropriate level.
If it doesn’t turn off automatically, the next step is to press and hold your vehicle’s TPMS reset button until the TPMS light blinks three times.
If that doesn’t work, drive the vehicle at 50 mph for around 10 minutes, and the TPMS light should reset itself the next time you turn the vehicle on.
If all else fails, please contact your trusted Nissan service center.
