2003 Toyota RAV4 air fuel sensor location
Gents, I've read numerous threads on RAV4 air fuel sensors, but the one question I still have is where is it located?
I/we replaced an O2 sensor near the bottom on the engine on the driver side, but we still get an air fuel sensor error message (P1135) but the manual doesn't tell you where it is. Is it one of the upper sensors? If so, which side, driver? passenger?
I've even seen drawings that show it in front of the catalytic converter, but there isn't one there, they're all up front.
So, of the four sensors up front, and with the bottom 2 being O2 sensors, which of the two upper are the air fuel sensor?
Thanks. Any help you can give would be greatly appreciated.
