Q: I put air in all my tires, but the light is still on. What’s going on?
A: First, double check that you inflated all your tires to the appropriate PSI listed on your vehicle placard inside your driver’s side door. This includes any full-size spare tires. If a tire keeps losing air pressure, or the light comes back on a day or so after you fill your tires, you will need to seek immediate repair, as there is most likely a leak in one or more tires.
Other reasons for the TPMS light to come on and stay on are:
• A dead or failing sensor battery.
• A TPMS module not receiving signals from one or more sensors because of an antenna or wiring fault.
• A TPMS module is not functioning properly or has failed because of a voltage supply, wiring or internal electronics fault.
• Corroded valve stems could also be causing issues with the system, or the tire’s ability to hold air.
