    Which oxygen sensors control fuel adjustment?

    I would need to replace both of them? Could the sensors not cause the engine light to go on or throw a code?

    Which oxygen sensors control fuel adjustment?

    Hey all, I have a 2004 lj unlimited. I am having horrible fuel mileage... I changed the water temp sensor did not change a thing so the next is oxygen sensor or vaccum leak. For the sensor which one would be the problem.
