toyata 2009 siena tpms tight on

Question

my 2009 toyota siena tpms light is on. is there any way to tell which one is bad? I think all tires are good. so i guess the one of the sensors is bad. These sensor simply caused trouble. I replace one of the sensor already and it's expensive.

Thanks!

Answer 1

You need a scan tools to determine which one is bad or a TPms sensor reader,, most tire shop has TPMS reader , that can be used for you. If you installed a new TPMS sensor you need to flash into the ECM ,Also check the spare tire.
