Low tire pressure light stays on

Is spare tire equipped with a pressure sensor and if so, inspect tire pressure for the spare

If you had tires installed and light stayed on it is possible not having spare but normally the tps sensor (tire pressure sensor) or tpm tire pressure monitor or it got damaged when new tires got installed.

TPMS - TIRE PRESSURE MONITOR WARNING LIGHT
NOTE: Tire pressure rises and falls depending on heat caused by vehicle's operation and the outside temperature. If outside temperature is low, the air inside the tire may cool, causing a lower tire inflation pressure. This may cause the low tire pressure warning light to illuminate.

When the tire pressure warning light comes on, immediately check the air pressure of all tires and adjust to the specified pressure. Make sure the warning light goes off. If the warning light stays on or flashes, there is a malfunction in the TPM system. See appropriate manufacturer service information.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

32 psi is the usual recommended pressure but you may have to fill the tires to 35 psi to make the TPM system reset. That's how most systems recognize that you have serviced the tires. Most TPM systems will indicate low tire pressure around 26-28 psi.

Hi, this is indicating a low tire pressure issue. The first thing to do, is check all of the pressures, according to the list on the label of the driver door. I say check all, because, if you have had the wheels off, new tires, brakes, or rotations, the relearn may not have been done, and the tire positions, may not be as described. So check all pressures, and if 1 is low, this is the issue. If they are all good, and the light persists, you need to visit the dealer, as you may have a problem with a sensor. Good luck...Coop

It sounds like the sensor inside the tire is may be defective.

the system will monitor all 5 tires. if one is 3-4 pounds differant or 1 of the tires are missing it will come on. doesn't matter what tires you have because the valve stem does the work.

Must have engine computer scanned to get codes and determine cause of check engine light. Low tire light probably needs reset. Open passenger door and remove panel on side of dash. Reset switch should be located in that compartment.

Your nissan also has a tire monitor on your spare tire if your spare has low pressure and the other 4 tires have correct pressure the light will stay on . after you ajust the spare also the light should go away.

32 psiis actually low for a 3500. I have a 1500 silverado that runs 44 psi cold. The tire inflation monitor , monitors inflated cirunference. Sooooo, If it isn'nt round enough, it will let you know. Driving warms up both the air and the tire,off course changing everything again. Pressure is up and tire is bigger. Ask me not how it can tell what is going on with the tire sitting still. I'm only on page 9,000, the answer is here somewher. :-) Well good luck. I do know the above is accurate._Ned_
