When the TPMS light stays on, it's indicating a problem with the system. What you would need to do is have the codes read with a scan tool capable of reading BCM codes. The most common problem is one or more of the TPMS sensors has/have failed. Each sensor has it's own battery that is non-serviceable, so you have to replace the sensor when the battery does go bad. Generally, the sensors are good for around 6 or 7 years, +/-. If all of the sensors are original, chances are that the others aren't far behind, if they are still good. If this is your case, I would recommend you replace all four sensors. My choice for replacements would be Dorman TPMS sensors. You can get them for about $40 each at Rockauto.com, or half the price of genuine Nissan sensors, and they have a lifetime warranty. The sensors will need to be ID registered, which requires an activation tool and a capable scan tool. The dealer can do this, as well as some tire shops and independent repair shops.
