Oxygen Sensor Error Code P0161
P0161 is the error code for a bad sensor reading in the Left Side Downstream Sensor, which is what I am getting on my code reader when hooked up to my 2003 Montero Limited.
Some vehicles have fuses for their Oxygen Sensors and sometimes it's the fuse that has gone bad and not the actual sensor.
Can someone tell me if the 2003 Montero Limited with the 3.8L engine has fuses for the Oxygen Sensors?
I have looked in the manual, in the vehicle repair guide, and have searched a ton online and am not seeing any fuses for this scenario in my Montero.
Let me know what you guys think.
Thanks in advance...

I've gone ahead and order a Denso 234-4633 Oxygen Sensor for Bank 2, Sensor 2 and am going to change it out this weekend.
I don't think there are fuses for the Oxygen Sensors on my Montero. If you know differently, please chime in.

I don't think there are fuses on Montero O2 circuit. You ether have a bad sensor, or a problem with the wiring to the sensor. If installing the new sensor does not fix the code. trace the wires to see if you have a brake or a chaffed wire that shorts out on the frame somewhere causing circuit malfunction.
