I have a 2008 Dodge 1500 Mega Cab 4X4. My Tire Pressure Light came on but no audible sound was heard. I check all the tires even the spare and they have all the required air pressure. The light still comes on when i start the truck but at no time does the audible sound come on.
Any help please??
Thanks

 

Could be the batteries have died (not likely this soon) or the receiver has lost contact with the sensors. Have the tires been worked on lately? Does your TPMS show that a tire is low, or does it show which tire is low?

 

Check for cracking on the valve stems and/or nuts sticking out of the rim.
