Default P0037 check engine and VSC light on

On the road today and out of no where I see the 2 lights 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.

Very nice read. Thank You

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?

Also make sure the sensor has not come loose. The reason I'm saying this is my sensor was loose from the threading and it was throwing codes. This was a relief when I got the news after dropping the vehicle off

Bank 1 is firewall side, sensor 2 is the one after the cat that is attached to the manifold...

This morning I made it 2 miles and it threw the same 2 lights.

Thanks to all the help I have received in this thread it looks like I will have no problem fixing this issue. Thank you so much for your helpful advise and links.
