Why is the low-tire pressure icon still lit up?

Why is the low-tire pressure icon still lit up?

Q: I had a low-tire-pressure icon illuminate on my dashboard when it got cold outside. I waited quite a while to address it, had the tires looked at, and filled them to capacity. They all needed a little air.

In the past when this would happen — after driving a short distance — the icon would disappear. I’ve driven it a few hundred miles, and the icon still is on. Do you have any suggestions?

A: Depending on the system (direct or indirect) there could b e a faulty sensor, or the system needs to have the TPMS reset.

After all the tires are checked with a gauge (also check the spare) and inflated to the proper pressure, most systems will reset.

If the system is an indirect type, look in the vehicle owner’s manual for a TPMS reset procedure.
