Q: What does code P2BB0 mean?

Alternative Fuel Consumption Too Low. P2BB0 is a generic powertrain code indicating that the engine control module has calculated the vehicle's alternative fuel consumption to be lower than expected for the current operating conditions. The computer monitors the rate at which alternative fuel is being used, often by tracking the fuel level sensor or injector pulse width, and sets this code when the consumption falls below a calibrated threshold for a set period.
