P0037 - Bank 1 Sensor 2
I've got a 2009 Yaris Sedan - 164k miles. I bought it (private party no warranty ) back in September of 18 and in October I got the P0037 code. I just now got around to messing with it and I can't seem to find the connection from inside the car. I've removed the center console and I can't find downstream O2 connection anywhere! I'm in desperate need of some guidance on where I can find this connection to get the O2 sensor changed and get rid of this dang code!

You talking about the sensor located in the exhaust pipe?

Look under the car, follow the wiring from the sensor that is behind the catalytic converter.

Page EX-3.
https://cardiagn.com/1nz-fe-engine-exhaust-2007-yaris/ IMHO. Change both (upstream and downstream) sensors together. They work together better if the are both the same age. I know they cost more, but buy OEM/Denso parts. You will regret cheaping out. https://www.rockauto.com/en/catalog/...2)+sensor,5132 |

Thank you guys so much. I was about to say F*** it and never change them. I got the pre-cat sensor just fine, but trying to get the post-cat was making me crazy!
