I have a 2004 4.2 V6 engine code P2195 comes up on the obd code and it says 02 sensor signal stuck. It also says Lean Bank 1 sensor. Where do I find the 02 sensor?


It's in between the engine and fire wall. Bank one sensor one. To access it you have to remove the windshield wiper box. Remove the wiper arms, remove the upper bezel under the arms( screws to remove), pull it our. There are nuts at the top and bolts at the fire wall to remove(about 10 total). Unplug the wiper motor(on the driver side) pull it out. Then in the middle of the engine look down, you will see the O2 sensor. 21 MM special socket gets it out. Check wires for melting first, then check the plug for corrosion. Fix as necessary. Your O2 may still be good.

Where is O2 sensor bank 1 sensor 1 located.


Should be Driver's Side front, You may need a special socket to remove it if you can reach it with a wrench. Be careful the threads can come out of the hole sometime with the sensor. Do not try when hot!

How to change oxygen sensor


1. Special open sided socket to thread the wires I do not know you size but they are available at most auto stores
2. Torch to heat the pipe! O2 sensors are under tremendous heat and the exhaust pipe needs to be heated around the O2 sensor to expand the pipe so you can get the old O2 sensor off.

O2 sensor needs to be replaced can it be done by owner


Yes an owner can replace an o2 sensor.
It may require a special socket which is avaialable at auto part stores

Below is a list of items to consider that are from an autozone site
  • The sensor is threaded into the exhaust manifold.
  • It can be difficult to remove unless a special anti-seize compound is coated onto its threads.
  • Torque the sensor to 30 foot-pounds using a special socket.
  • A sensor that is too loose or a cracked exhaust manifold can result in a lean signal to the computer.
  • Check the vents in the thimble of a replacement O2 sensor.
  • There should be the same number of holes and they should face clockwise or counterclockwise like the ones on the original sensor.
  • Installing the wrong sensor can result in slower cross counts.

Where is the o2 sensor and how do you change it


On the exhaust manifold. Put some type of rust buster on it and let it sit overnight before trying to break it loose. There may be a second O2 sensor after the catalytic converter.

How do you replace the O2 sensor ?


You need to find which is bad. It can be removed with a 22mm wrench or a special oxygen sensor tool. disconnect the battery, and the sensors will be located in the exhaust manifold and at the exhaust converter. You will unplug the O2 sensor and loosen with the tool, once it is loose, it's easier to finish removing by hand. Make sure the car is cool down. Before replacing it, make sure it has anti-seize grease applied to the threads of the new 02 sensor.

It should not be too hard but there are special sockets to clear the wire, you might get by with a wrench of the correct size, they are either side of the bulge in the front exhaust pipes (the cat converters) and either side of the transmission, are you sure you need all 4?

Where is the O2 sensor on a 1999 Ford F-150?


Auto Zone has information on the O2 Sensor for your pickup here. It is located somewhere either on the exhaust manifold, or on the pipe leading from the manifold to the converter. If you're going to replace this yourself, get the special wrench to remove and replace it -- it's cheaper than having to get another sensor if you break the new one using the wrong tool.
This shouldn't have anything at all to do with your airbag.
