Hi Mr. Pro,
I read "SFI communication" in Yaris's manual book.
Could you tell me what is SFI communication?

I appreciate your help.

SFI is typically "Sequential Fuel Injection" used in newer cars because of emmissions concerns (it is more presice than other types).

Are you getting a check engine light?

Communication errors are "U" codes, and can be read with high end scanner.
