tpms, older wheels question

[ron3]

I have a 2012 LE and want to install a set of 10 spoke wheels off a 2004-2007 Scion Not sure if the sensors will fit the scion wheels, my questions is If I don't install wheel sensors will the little yellow light be the only issue, or will I get a check engine code, also will not having the tire monitoring system working effect my warranty.

The yellow light will be your only issue. The TPMS is not considered a fault for the engine related diagnostics.

If you go for service and the light is on and they see that you are running non-compliant rims, they may give you a hard time. In reality though they can only refuse warranty repair of anything directly effected by you running the rims.
