2011 Dodge Caravan - testing tire sensors

How do I determine if my vehicle has a bad “low tire” sensor, as all the tires are pressures are as they should be?

You can take it to a tire place. They can check to see if they are all transmitting.

If there is a fault detected like a failing tire pressure sensor the tire pressure light will flash for 75 seconds each time the engine is started, then remain on.
