2009 g37 convertible. I was driving down the interstate around 75 mph felt my vehicle immediately lose power. I coasted to the shoulder, my motor was still running but now response from the pedal at all rpms wouldn’t go up or anything. I disconnected the negative and reconnected it and that allowed me to drive like a mile further until I had to accelerate up a hill then the same thing. I got two codes off my scanner P2A00 and P0051. Has anyone had this issue? Is it possible that my 02 sensor failed causing complete loss of throttle response? Try not to roast me on here, I am an aircraft mechanic not a car mechanic. So if it’s a simple fix I can most likely turn the wrenches to fix it myself
