I need to replace the oxygen sensors in my 2005 Aviator. Advanced Auto parts said that my Aviator has four of them but they couldn't tell me where they were. They said that they should be easy to change though. Any ideas of where they are?
Here's the Aviator oxygen sensor location diagram that you'll need. They are easy to change, just make sure not to break the clips that hold the pig tails of the wires together.
One pair of oxygen sensors on the Aviator are slightly past the exhaust manifolds and the other two are behind the cats.
