yea, that upstream o2 they swapped on mine has kept it away also as i said. thanks for looking into the notice!
You bet. Just sucked dealing with mine because the O2 data appeared totally in spec with mine. I talked with several dealership techs that started off diaging a P1128 by replacing the upstream O2 first, and that didn't fix theirs. But then, the way the O2 data is shown live in the dealership scan tools (WiTech) the lovely engineering dept decided to change that all up. Probably most in part to these having a wide band O2 sensor now, not the older type. Hopefully they change that so the live data is easier to look at and translate.
I replaced the upstream O2 sensor at the top rear of the engine. Doing so served to extinguish the P1128-linked CEL in my Jeep. Just an FYI.
same for me. 25000 miles since
Do you have a part number?
Jeep was under warranty so the dealer handled it. yours should be under warranty too.
I’m out of 3 year. Is this covered by 5year warranty?
good question, I'd have thought powertrain because its emissions based, but Google says bumper to bumper. best to call them.
Confirming that the bolded part # is correct here. That's also what I used.
the CEL was off after 10 minutes drive.. probably I'll end up like you : )
oh yes its good fun when its intermittent! im sure its that o2 sensor then !
