TPMS stands for "Tire Pressure Monitoring System." The Nissan Titan is equipped with this feature. This system checks the truck's tire pressure at specific intervals. If the tire pressure is too low, a "Low Tire Pressure" light will appear on the dash. There is no button to manually reset this system. According to the Titan's owner manual, the tire pressure must be checked, and the truck must be driven to reset the system.
Drive your Nissan Titan to a service station that has a tire-inflation or air machine. Many convenient stores have these machines. If you have an air tank or an air compressor at home, you can simply perform the procedure in your driveway.
Turn your Titan's engine off and step out of the vehicle. Unscrew the valve stem cap on the driver's side front tire. Attach the end of the pressure gauge to the stem. View the reading on the gauge. The reading should be 35 PSI.
Attach the air hose from the compressor, tank or machine to the valve stem and add a bit of air. Check the tire pressure again. Repeat the process until the tire's pressure readout shows 35 PSI. If the readout was initially too high, touch the center of the valve stem with the back of pressure gauge to release air from the tire.
Repeat for each tire. Ensure that each tire is at 35 PSI. Verify that you've replaced all of the valve stem caps when you are finished.
Drive your Titan for about 15 minutes at a speed of at least 15 miles per hour. During the driving cycle, the TPMS resets. Your "Low Tire Pressure" light should go off.
