Service TPMS Warning Light

[wilsonjr32]

TPMS light started flashing & my DIC read 'service TPMS'. After a while it stopped flashing & just stayed on. The system corrected itself & the light goes off and the sensor is reading pressure again. Whats going on?

It could be a defective sensor. If the light is solid, there is one or more tires with pressures that need to be adjusted. If it is blinking, there is a malfunction with the system and the Sensors need to be replaced. From what you have said, it would seem that you have a defective sensor. It would be best to replace all 4.
