Hello, I have a 2011 Gen1. I have a code P219A that shows as "Historical" using torque Pro. I changed the O2 sensor about 7 days ago, drove the car to work and all around town. I've tried mountain mode, not charging and going into low propulsion unit I get the 20% battery to back to hybrid. I've tried resetting the light driving 25MPH for more than 8 minutes then idling for 30 seconds and then shutting car off. The CEL turns off for a while then just turns back on sometime later. Anyone ever won this battle?
