Oxygen Sensor The O2 sensors on your truck. If you look inside the wheel wells behind the fender liner, right about where the frame is one O2 sensor, the other is underneath the truck 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…
where is the oxygen sensor location on a 1998 explorer bank 2 sensor
Where are the Bank 1 Sensor 1 oxygen sensor on a 1998 ford explorer?
Driver side, after converter.
driver side first o2 sensor
how do you install a bank 1 sensor 2 for an 1998 acura tl
pasenger side second sensor which is after the catylic converter
closest sensor to the motor
Bank 1 sensor 3 would be the O2 sensor after the catalytic converter.
Bank 2 is the passenger side exhaust, sensor 1 is before CAT and sensor 2 is after CAT.
There are three 02 sensors. The front left sensor is the forward most sensor, on the left bank of the engine. The next is the front right sensor on the right bank, the rear sensor is after the catalytic convertor. see below web site: http://www.courtesyparts.com/A32_O2-sensors.html
Bank #1 is the passenger side of the engine , and sensor # 2 is in the exhaust after the catalytic converter ( downstream )
your bank one sensor is the o2 sensor on the exhaust manifold bank one means that it is on the same side of the engine as the #1 cylinder (driver side for the v6 not sure on the v8)
