A/F Ratio (AFR) - Toyota Yaris Forums

Kaotic Lazagna · 02-04-2011, 08:41 PM

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.

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

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.
