Code P0037, 2004 Toyota Highlander says bank 1 oxygen sensor 2 is bad.

Question

The parts dealers ask me if i want the "left or right" or the "front or rear" when picking the part on web sites. Even the auto parts store asks which one.  Code P0037 says bank 1 sensor 2 but the parts dealers don't use those words. They use left and right or front and rear....

How do I know if it is left/front or right/rear?? And where is this sensor physically located?

Answer 1

P0037 Oxygen sensor heater control circuit low Bank 1 Sensor 2

Sensor 2 are the downstream 02 sensor or the catalytic convertor sensor.

Here a diagram for the 02 sensor you need on the right hand on the bottom of the diagram there the 02 sensor Because we are facing the engine to the front this make it the right side, So you want the right side lower or downstream,

​ Here your engine what is shown here is the left side, toward the back is the right side
