Fairly certain SA code for factory equipment you're asking about is 2VB.

Thanks for the links. They helped me understand how this system works and give me a direction to look into.

One question: In these discussions, someone mentioned that if the valve cover is metal, that means it's has the TPMS sensors. If the valve cover is rubber, then it's not. Can anyone confirm if it's true? Because I recall my valve cover is metal.

Any input on this is greatly appreciated.
