When this sensor gets clogged andor goes bad from rust and heat fatigue the voltage drops low enough to cause the electronic control module to register error code P0161 which then causes the check engine. I tried looking at the one that currently installed with a mirror and flashlight but cant find a part number on it.

Upstream sensor located before catalytic converter Notes. To meet federal emissions standards Toyota placed an oxygen sensor before and after the catalytic converter on the left and right exhaust piping. The upstream oxygen sensors are located on the lower base of the left and right exhaust manifolds.

I should known better then to test drive the new ones. Searching the various online Toyota parts sites there are 2 part numbers listed for the right front. Heated oxygen sensor heater control circuit low bank 1 sensor 2 Is there a fuse for this or do I need to replace an O2 sensor.
