Q: TPMS Warning Light on

asked by on

The TPMS Light keeps turning on, along with the "!" Light.

The exclamation mark indicates a problem with the traction/stability control system. The control module monitors the wheel speed sensors to determine a low-traction condition. If low traction is sensed, the module will apply brake pressure to the spinning wheel, and modulate engine torque until the situation is under control. Since the traction control system is dependent on wheel speed, a problem with one of the tires, such as a flat or under-inflated tire, may trigger both the "!" and TPMS Warning Lights. I suggest you have all of your tires checked for leaks, and get your warning lights diagnosed. The professionals at YourMechanic are here to help, and can come to your home or office.
