Question P0037 Error Code

My camry 2008 showing check engine light on dashboard I went for computer scan and got error code P0037, now mechanic has said there are two sensors in car he recommend to get replaced both. Please have a look at following screen shot of error code.

Shall I replace both? Or can anyone please help me to understand what exactly this error code means?

What kind of engine, V6 or 4-cylinder?

For emissions and engine operational purposes, the engine computer monitors the 02 level of the exhaust going into and out the emissions converters. This is done using sensors before and after the converter. The sensor incorporates an electric heater much like a soldering iron uses to heat up the sensor probe.

The code means the computer has found the sensor heater is not working properly. This is based on the electric current flow of the sensor heater.

These codes are very specific as to what sensor has a problem. In this case the sensor located at Bank 1, Sensor 2.

Is there a reason the mechanic stated to change both?

Thanks for the reply.

I've automatic 2.5 v4. I feel like due to lack of experience he couldn't point out which sensor is not working. He showed me two sensors in car one is in bonnet near to engine 2nd one is below the car near to front chassis.
He changed the below one but check engine light still coming. Where is the Bank 1, Sensor 2? in bonnet or below?

Compare the replaced sensor with the location at the info below:

Can also be a blow sensor fuse, bad wiring, computer plus some sensors brands seem to work better then others.
