Hey all,
I’m getting an intermittent P1128 over the past week (closed loop fueling not achieved bank 1). Normally this code comes paired with an o2 sensor fail code or something that causes it to go off, but it’s solo. It also isn’t all the time. It’ll clear after a few ignition cycles when it doesn’t meet the conditions. Then pop back up. It also doesn’t pop up while driving, but within 30 seconds of start up. Must be when the closed loop fueling runs its test to come off the open loop for better emissions. I’m under warranty and will end up taking it to the dealer, but just looking to see if anyone has experienced this. 2020 JLUR 2.0 engine with 20k miles. No engine issues prior. Jeep drives great, so i doubt fuel filter or any of the actual “issues” that this code gets thrown for. Seems sensor related. I have the freeze frame from the JScan app from when the active light was triggered. Just unsure of which spec is out of compliance. Searching around here and google it doesn’t seem common. Or at least not written about on here.
