TPMS Flashing Light?

I got a 2010 double can with 245 stock steel wheels. I notice when I start the car the TPMS light starts flashing for about a few seconds then stays on. What does this mean? I put air then the next morning it came back on but I didn't fill up the spare tire. Help please thanks

 

Does the spare have a metal rigid valve stem or a rubber one?

 

@Silverspool just checked metal

 

theres a TPMS in then, air it up!

 

Could be a bad sensor. The sensors have a battery life of 6-8 years. Since your truck is a 2010 then I'm sure you're coming up on that time. I found them cheap here http://titantpms.ecomm-nav.com/nav/Year-2010--Make-Toyota--Model-Tacoma--Type-TPMS.

 

A flashing TPMS light that turns on solid after a minute or so indicates a system problem, that is, a dead sensor.

 

TPMS light flashing......could be?.....maybe?.....possibly?.....what if?.......try this?......etc., etc., etc.

Look up and read about TPMS in your Owners Manual, that is your "best source of info" pertaining specifically for this, on your problem.

Believe me it's in there.

 

I too had the same problem with my light. I could not get the sensors to reset after putting air in the tires. I ignored the warning light but noticed my truck was having trouble starting...like a bad 12volt battery. Took truck in to get battery analyzed found I had a bad cell and the starting amps were way low. Purchased a new battery for the truck and like a miracle, the TPMS light went out! I wonder ...
