2017 Tacoma c2121


Recommended Posts

tire pressures stopped reading. Drove like that for about 25 min. then TPMS icon began blinking after about 39 sec it went solid. Found fault c2121, cleared it problem went away,

but I think it will return. I don't know what triggered that fault, all tire pressures read the same 32psi. 

Any idea what triggers that fault?
