cel again

[2000 elantra]

OK here we go agaim.The o so annoying code p4022 poped up todayIt has been 12 days since I reset the ecu and put in the spark plug fowler for the rear o2 sensor.On my way to work it kicked on this morning.Does anyone know how to fix this since the fowler didn't seem to work.If I move the cat behind the felx pipe instead of after it will this work or will I need to extend the wires for the o2 itself and just relocate it.

Our car's are so freakin sensitive about throwing cel's! Wish you could just disconnect that light sometimes. Mine went off 6 times in 3 weeks before I got fed up and went to the dealer. Since the time I went before and had reset the ecu myself and they told me the sensor was fine, I went back w/ the light on and they replaced it. Sorry for flaming in your thread, but that light does suck.

Hmmm so is your secondary oxygen sensor before, or after the primary (or only) cat?

[2000 elantra]

one sensor is on the header then it comes down to the flex pipe and then the o2 sensor is right their and then the cat.should I try to move the cat befor the flex pipe or will it not fit

[sciphi]

IDK if that would fit. The space down there is really tight.
