While cruising on a 120kmh on small country side road, busy navigating and overtaking cows, tricycles, crossing pedestrians suddenly my TPMS let out a long alarm. Its my first time to hear it and have no idea what is beeeeping and then I realized it must be my TPMS after it went away.

What could be the problem? I live in a tropical weather so there's no way it could be the cold climate

 

I don't know what is going on with my tire the sensor keeps going off and it the front right passenger tire it loses air and set off the alarm every 2-4 days. How can i tell if the tire has a hole or if the sensor is defective letting air out of the tire? Has anyone had this type of issue?

 

Visual inspection of the tread for screw or nail heads. Screw heads will have a leaky seal and you can drive on them for a while. Nails tend to leak a bit faster in my experience.

If you can't see anything on the tread or sidewalls of the tire. Get a spray bottle and make up a dishsoap/water mixture. Inflate the tire to 32 PSI and start spraying the tread, sidewall, rim/rubber interface and around the TPMS sensor (valve stem).

Look for bubbles.

Sounds like the TPMS sensor is just doing it's job if you are losing pressure compared to the other wheels.

If you can't figure it out from there have a tire shop look at it.
