For seawater about 10ppb.
Oxygen, temperature, speed, throttle position.
Is a part of the emission control systems, these systems provided oxygen to oxidize (burn) unburned and partially-burned fuel in the exhaust before its ejection from the tailpipe.
the auto parts dealer said that it was 4 oxygen sensors on that car.the 1998 Lincoln continetal
2004 Lincoln ls has 4 oxygen sensors 2 upstreams and 2 down streams
An oxygen sensor does not control heat. It sends info to the computer about oxygen levels in the exhaust to adjust fuel injection amounts.
Oxygen sensors are screwed into the exhaust system.
on the mufflers after the heads
I had the same problem and it is your oxygen sensor.
You can replace the oxygen sensor on a 2002 lincoln LS by first unplugging the old one and then making sure the tread marks are lined up replace it with the new one.
