Loss of power, misfires 2000-3000 RPM, codes P2240 and P2237
This car is brand new to me, so I'm just going off what doesn't feel normal to me.
When accelerating, especially in higher gears under load, at 50% or greater throttle, there are noticable misfires in the 2-3k rpm range. You can feel it as the car is basically hesitating at each misfire. I don't want to describe it as a jerk, but you can definitely feel it. If I back off the throttle, I don't feel the skipping.
Sometimes it will throw an SES light. I pulled codes and the only ones that come up are P2240 (current) and P2237 (pending).
The torque app on my phone describes them as:
P2240 O2 sensor positive current control circuit/open bank 2 sensor 1
P2237 O2 sensor positive current control circuit/open bank 1 sensor 1
I couldn't find definitive answers online when I googled. People were saying they had their DMEs reprogrammed because they were "too sensitive". That doesn't seem like a correct fix.
And so often these O2 sensors end up being something else like coils, a vacuum leak, etc.
