yes, it's threaded into the front of the front catalytic converter. that's bank 1 sensor 1. (bank 1 sensor 2 is threaded into the rear of the rear catalytic converter. in order for the car (more specifically the computer) to refine how well the engine will run, and also to keep the amount of pollutants headed out the tailpipe down as low as possible [especially carbon monoxide (CO), hydrocarbons (HC), and oxides of nitrogen (NOx)], the computer constantly compares the two (in this case) oxygen sensor readings (while the engine & computer are running "closed loop") and alters/tweaks/maintains fuel, ignition timing, spark, cooling fans, etc., in order to maximize efficiency. i just googled "oxygen sensor info," and this is the first website i saw http://mr2.com/TEXT/O2_Sensor.html ; it might give you a little more background theory about O2 sensors and how they work, in case you're interested. my idea is that if you understand how they work, why they work, and how to test them, you won't throw away money replacing parts that don't need replacing. good luck. The 2000 Subaru Outback has 2 oxygen sensors. One is located at the front of the catatlytic converter, and the second is at the rear of the catalytic converter. My best guess is #1 is at the front, but I'm not positive here. I'm replacing both anyway as I'm at 100K miles. David
The Bank 2 Sensor 1 Air/Fuel Ratio Sensor is on the left side of the Left Hand Front Exhaust Pipe, just below where it connects to the engine. Can't miss, it stands out like a sore thumb.....
Right Hand Side (passenger side)...
The oxygen sensor for bank 1 sensor 1 for a 2000 mercury mountaineer is on the cylinder #1 side.
bank 1 sensor 2 is after the cat
Bank 1 sensor 2 would be the sensor after the behind the catalytic converter.
The 2000 Mazda Miata O2 sensor bank 1 is located on the firewall in the engine compartment. The sensor can be found on the passenger side of the firewall.
bank 2 sensor 2 is the passenger side, rear sensor, it is located behide the catalytic converter.
That should be the sensor after the catalytic converter.
Bank 2 is the side of the engine that faces the front of the vehicle, sensor 1 is the upper sensor, it is in the exhaust manifold
That should be the sensor located after the catalytic converter.
need change knock sensor 2 bank 2 in 2000 lexus rx300
Bank 1 is the driver side.
2000 jimmy 4.3ltr v6. were is the o2 sensor bank 1, sensor 3
Bank 2 is the drivers side of the engine Sensor 2 is in the exhaust pipe after ( downstream ) the catalytic converter
BAnk one sensor one is above the cat on the back exhaust manifold. Sensor two is below the cat.
bank one is drivers side, sensor 2 is rear O2 sensor(oxygen sensors are screwed into exhaust pipes)
Bank 1 refers to the location of the bank of cylinders that contain the #1 cylinder. Sensor 2 refers to the Oxygen sensor after the catalytic converter. Bank 1 is the left side of the engine, in this case against the firewall, and Sensor 2 is past the catalytic converter on that bank.
Bank 2 is the drivers side of your engine Sensor 2 is in the exhaust after the catalytic converter ( downstream )
Bank 1 is the bank of cylinders that has contains the number one cylinder which in your case would be the drivers side bank of cylinders. The O2 sensor for bank 1 sensor 1 is located in the exhaust pipe directly after the drivers side exhaust manifold.
The 4.0L can have one or two banks. If it has two, bank one sensor one is the sensor closest to the front that is screwed into the exhaust manifold. If only one bank it will be the only sensor in the exhaust manifold.
Bank 1 is the passenger side of the engine in your 2000 Ford Mustang V6 Sensor 1 is before the catalytic converter ( upstream ) Sensor 2 is after the catalytic converter ( downstream )
Bank 1 is the bank of the engine that contains #1 cylinder. Bank 2 is the other bank. Sensor 1 is located before the catalytic converter. Sensor 2 is located after the cat converter.
Bank 1 refers to the side of the engine where the number 1 cylinder is located and sensor 2 is the down stream or after the catalytic converter sensor.
02 Sensor, bank 2 no activity.
It is the sensor in the outlet of the catalytic converter.
