Frank that code is Bank 1 Sensor 1 too lean (not too rich). If it's happening only on the highway, then possibly it's starving of fuel supply causing a low power condition and relying only on battery which depletes quick. Usually the strainer filter on the fuel pump assembly in the tank gets clogged over time from using fuel cleaner additives and bad gasoline. Remember the P2196 is the rich version of that code. We just did a fuel pump on a vehicle with the same code and it fixed it completely after chasing O2 sensor/Catalytic converter down a rabbit hole. They are about $400 or so but it just might fix that condition and code for you. Let us know.

That’s interesting theory…Do you think that fuel pump strainer/filter can be cleaned up a bit… instead of fuel pump replacement?
