Posted to Asian Driveability on 7/17/2009 7 Replies

Hi I have a 07 Toyota sienna van with p0051 and a p0158 and p2197 codes I have no toyota info and have no idea where to start. Looks like I should replace the Bank 2 sensor 1 AFR sensor. Does anyone have any service info on these codes?

Thanks Jason
