Q: TPMS light is on. What does that mean?

asked by on

The TPMS light is on.

Hi there. The TPMS light can come on for several reasons. Most of the time it comes on for low tire pressure. You need to check the tire pressure and make sure that all four, including the spare are filled up to the specifications in the door. If the light remains on then there is a fault in the system. This can occur from a bad sensor or lost communication. It will take specialized equipment to replace a sensor and reprogram the system. You will typically need to enlist the help of a certified mechanic, like one from YourMechanic, to perform this task.
