P0037 check engine and VSC light on
So I get home and find the port for the scanner. plug it in and retrieve the P0037 code.
I cleared the code and I'm hoping it will not come back.
What exactly does the code mean? What might I be looking at in my near future?
Car has 109K and I have not had it serviced since 85K except oil changes. I use shell 93 octane gas. car sees lots of highway when I'm using it. 2004 RX 330 AWD.

I'm glad to see that it is most likely the sensor and not the Catalytic convertor.
Now I just need to find out which side bank #1 is and where sensor #2 is on the exhaust system.
The read also said something about a voltage fluctuation could be the cause. I recently started using my heated seat for the first time. lol
My battery is over 3 years old and might be needing replacement as well.
Problem is it is so F(^King cold here right now. Not want to climb under the car right now. I do suppose I could throw the load tester on the battery though.

I also hate just blindly changing parts without true conformation.
Has anybody received this code and change out the sensor while solving the problem at the same time?
