Oxygen Sensor If you look inside the wheel wells behind the fender liner, right about where the frame is one O2 sensor, the other is underneath about half way back in relation to the transmission. If you see where the exhaust joints together, you went about 6" too far.
When you start looking at the O2 sensors, they are normally numbered something like "Bank 1 Sensor 1" Bank 1 is on the passenger side; Bank 2 is on the driver's side. Sensor 1 is the upstream sensor (near the frame, between the block and the cat) and Sensor 2 is near the Y-pipe (downstream of the cat).
Normally it is the upstream sensors (sensor 1) that go first. They see the harshest conditions. You will need; Oxygen Sensor Socket Anti-Seized Penetrating Oil Sometimes it will take 15 minutes or take a few hours it depends on your luck…
Catalytic converter failure bank one.Catalytic converter failure bank one.
Catalytic converter efficiency failure bank 2.Catalytic converter efficiency failure bank 2.
you must be refering to the catalytic converter for bank one which is refering to the left or right bank of the engine
The catalytic converter is behind the engine.
Bank 2 catalytic converter efficiency failure.Bank 2 catalytic converter efficiency failure.
Bank 1 catalytic converter efficiency failure.Bank 1 catalytic converter efficiency failure.
On a Lincoln Navigator : Bank 2 is the drivers side of the engine * sensor 1 would be close to the engine BEFORE the exhaust enters the catalytic converter
On a 2000 Lincoln Navigator : Bank 2 is the drivers side of the engine Sensor 1 would be close to the engine before the exhaust enter the catalytic converter ( upstream sensor ) Sensor 2 ( downstream sensor ) would be in the exhaust after the exhaust exits the catalytic converter
Bank 1 is the oxygen sensor either screwed into ,or above the catalytic converter. Bank 2 is below the catalytic converter.
where is the catalytic converter located bank 2 for 97 Nissan altima
That would be the O2 sensor after the catalytic converter. This sensor monitors the efficiency of the catalytic converter.
On a 2003 Lincoln LS or Lincoln Town Car : Bank 2 is the drivers side of the engine Sensor 1 would be close to the engine BEFORE the exhaust enters the catalytic converter
