A/F Ratio (AFR)

[Kaotic Lazagna]

Hey guys. Does anyone know if the AFR gauge on the SGII will work on the Yaris? I'm not sure if I'm plugging in the right one. I used the alternate AFR (general) under the ISO section: http://www.scangauge.com/support/pdfs/XGAUGE.pdf


Am I using the wrong codes? Nothing was displayed when I inputted the codes. Thanks in advanced.

This is probably a proprietary PID of Toyota and wont be listed , in addition it probably is accessed through a different command code. My ELM327 gives me all the general PIDs but nothing from Toyota, I mean it can read them we just don't know how Toyota coded these PIDs

Correct. With my YarGauge I read AFR via a proprietary Toyota CAN ID that I reverse engineered from the TechStream tool.

Dang, so it's not possible then with a SGII. Wishful thinking. lol. Thanks guys.

What is a "PID" anyway?

PID means "Parameter ID". The OEM proprietary ones require communication with different CAN bus IDs, which is the part that most aftermarket code readers don't have the ability to do.
