Today, i found the light of tmps is flashing on, i check the four tire pressure ,it is right pressure. so how to reset tmps for dodge caravan 2012?

 

if the light is on solid...its just low pressure and you can top up. When the light is flashing, there is a system problem. you can't reset it without a tpm registering tool.

if one of the sensors is not displaying a pressure in the evic...it may need a sensor. have a shop try to register the sensor...if it does not respond...replace it.
