Tire pressure must math that on the drivers door sticker, other wise it will not reset. After you set the proper pressure you must drive the vehicle for several minutes above 25 miles/hr to activate the TPMS and turn off the low tire pressure warning light, If you have the sensor replaced you have to take it to the dealer or a discount tire shop to have it activated to your vehicle
SOURCE: TPMS error light on, dash shows no readings
It has to be done at the dealer with the handheld computer. They have to access the Body Control Module and then go around to each tire with a unit that looks like a garage door opener and hold it on the tire below each valve stem. It should only take like 15 minutes to do.
SOURCE: Tire pressure light is on
You cannot reset them,Make sure that you check the pressures in the tires. The Infiniti Tire Pressure Monitoring System is designed to trip the warning light anytime the pressure in any of the tires drops below 29 psi. At 29 psi it really won't look like the tires are low. You could have one tire at 29 or 28 causing the light to stay on all the time. Check your pressures, set at 34 or 35 to be safe, or whatever pressure the tire is recommended to be. Not all infiniti vehicles with TPMS have the display that shows the pressure in each tire. If the pressures are above 29 psi, Then there could be an issue with one or more of the sensors. If you have the tires replaced you will have to have the sensors relearned at the dealer. Tire rotations do not require the same.
