Hey all,
2012 rubicon 79k miles
Went to get car inspected, failed due to the notorious “fuel system not ready” all monitors green, except for fuel system! Upon doing research i found this is a common issue, and the fix is to get the PCM updated/reflashed.
Did this, and now all monitors are green, fuel system monitor is green.. but OXYGEN monitor is now showing “not ready”
I have no check engine lights, the jeep runs great, it’s like i traded fuel system not ready, for oxygen sensor not ready.
Has anyone had this issue before? I’ve driven almost 200 miles since the PCM reflash, I’ve followed drive cycle instructions such as idle for 5 mins, accelerate to 30-40mph, etc.
I can’t seem to get oxygen sensor monitor to “ready” weird thing is, before the reflash, this was at “ready”
Any help or insight would be truly appreciated!
