Hi All,

I wanted to check and see if P1137 error code existed for the 2001 Lexus RX300. I've tried researching it online and haven't been able to come up with anything. P1137 was the error code that the Valvoline oil change guy gave me when I was getting my express oil change. Please let me know if anyone has any experience with this error code and what parts I'd be looking at to make it go away. Thanks all!

Well the P113X series, 1130, 1133 and 1135 point to the bank 1 sensor 1 A/F sensor behind the engine block. It's not a Toyota/Lexus code. I am also not sure what kind of scanner the person was using, but if you can find someone else with a scanner that can at least show readings on the 2 banks, then you can see if the readings are off there. There's not a way to shut it off if that sensor is having issues. Did you pull the the cables and reset the code and it still came back.

This is the bank 1, sensor 1 A/F sensor, https://www.clublexus.com/forums/5304307-post32.html
