I have a 98mitsubishi montero my check ingine light is on i hooked up my computer to read the code it reads bank 1/2 P0161oxygen sensor which oxygen sensor is the one on the driver side or passenger side


Bank 1 is on the side that cylinder number 1 is on, and 2 is on the other . Look up your firing order and you should find it fairly easily. And sensor 1&2 refers to before or behind catylitic converter.

Can an O2 oxygen sensor effect another sensor and give a false reading?


Check which side of your engine has cylinder #1. That side is bank 1. Bank 2 is the side opposite of bank 1. So bank 2 is not always passenger side. And since you seem to have extra O2 sensors, I would replace the other upstream and see what happens. Also the mass air sensor can give a trouble code issue to the upstream 02 sensors. Good luck. I've struggled thru this myself.

Question; Is the right side of a 2006 Toyota Tacoma V6 engine on the driver side or passenger side?


the banks of a v engine are determined from the drivers seat in a convention car and in a east-west car the no 1 bank is closest to the firewall so from the drivers seat no 1 bank will be in front of the driver ( LH drive cars) or in front of the passenger in RH drive cars

Whats the difference between up and downstream sensor on a chevy s10 1997, what exact sensors do i need for bank 1 and bank 2 sensor1


Well upstream from the Catalatic Converter means towards the engine and that would be the location for Sensor #1 on both sides of the engine. And Downstream would be away from the engine past the Catalatic Converter For Sensor #2 on both sides of the engine. Bank 1 or Bank 2 would indicate which side of the engine the trouble is on. ( Bank #1 is the side of the engine that contains #1 Cylinder. Please remember if you are going to change one 02 Sensor then you should change all of them and be sure to clear all codes after all repairs are finished. that will turn the check engine light off. Good Luck and have a good XMASS.

Which side is bank 1 in dodge durango 2000 4.7 the driver side or passenger side


I assume bank 1 is the o2 sensors before the cat & bank 2 is after the cat. The various auto parts stores
are giving me conflicting info as one store says bank 1 is the left cat and bank 2 is the right cat.

O2 sensors in a 97 gmc 1500 with 5.7 liter


bank 1 is the drivers side bank, so b1s1 would be the drivers side closest to the engine. if the truck is equipped with several 02 sensors then bank 2 or b2s1 would be passenger side closest to the engine. those are called upstream o2 sensors and the others downstream b1s2 and b1s2 b= bank 1= drivers side s=sensor 2=downstream. hope this helps.

Where is bank 2 sensor one on a Cadillac CTS?


Bank 2 Sensor 1 is on the driver side - follow the right side of the engine down the headers which attaches to the catalytic converter. The o2 Sensor you're asking about (Bank 2 Sensor 1) is before the Catalytic. The o2 Sensor after the Catalytic is Bank 2 Sensor 2. Bank 1 Sensor 1 is on the passenger side as well as Bank 1 Sensor 2.
