TIRE PRESSURE LIGHT ON AND OFF

2006 Jeep Commander • 84,000 miles

I have a 2006 jeep commander that had a tire going low so the tire pressure light would come on and go out when I aired up the tire. I took the tire off the truck and plugged a nail hole and put pressure back up to spec and now the light stays on. Do I need to reset it somehow and how do I do that or could soething else be wrong

The pressure sensor in the tire maybe bad

RESET PROCEDURES
NOTE: If a tire pressure sensor has been replaced, the tire pressure sensors must be retrained. See TIRE PRESSURE SENSOR RETRAINING.

TIRE PRESSURE MONITOR WARNING INDICATORS
NOTE: Tire pressure may increase from 2 to 6 psi (14 to 41 kPa) during normal driving conditions. Do NOT reduce this normal pressure build up.

If warning light is lit continuously due to low pressure in one or more tires, adjust tire inflation to specification. The light will remain on until tire pressure is properly set. After adjusting air pressure in a tire, allow approximately two minutes for the message or indicator lamp to go out.
If warning light flashes on/off for 75 seconds, then remains ON continuously (for 2006-2007 flash on/off for 60 seconds, every 10 minutes), there is a problem in the TPM system. See appropriate manufacturer service information.
TIRE PRESSURE SENSOR RETRAINING
NOTE: If a tire pressure sensor has been replaced, the TPM system needs to relearn tire pressure sensor IDs. For a normal road wheel, see ROAD WHEEL. For the spare tire, see SPARE TIRE.

Road Wheel
Using a RF signal, each sensor transmits tire pressure data approximately once every minute. Each sensor's (transmitter# broadcast is uniquely coded so that the WCM can monitor the state of each of the sensors on the 4 rotating road wheels. The WCM automatically learns and stores the sensor's ID while driving after a sensor has been replaced. There is no formal retraining procedure necessary.
Drive vehicle for a minimum of 10 minutes while maintaining a continuous speed above 20 MPH #32 KM/H# for 2006 models and 15 MPH #24 KM/H) for 2007-09 models. During this time, the system will learn the new sensor ID code and will clear any DTCs automatically. If a sensor cannot be trained, see appropriate manufacturer service information.
Spare Tire
NOTE: To program the tire pressure sensor ID for the spare tire, a diagnostic scan tool must be used.

Copy the ID number off of the new pressure sensor before installing it into spare tire. Then follow the programming steps outlined in the scan tool for: "LEARN SPARE TIRE SENSOR ID" under "MISCELLANEOUS FUNCTIONS" for the "WCM/WIRELESS CONTROL MODULE" menu item as appropriate.

It was working properly til I took off tire and plugged and then reinstalled now it just stays on with proper pressure
