P00B9

DTC P00B9, sometimes indicated as P00B900 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing low pressure fuel system pressure - too low, low ambient temperature.

The low pressure fuel system pressure - too low, low ambient temperature code is set when the fuel system pressure is below the specified limit. This may be caused by a low ambient temperature, a fault in the fuel system, or a blocked fuel line.
To fix this code, you will need to identify and fix the underlying problem.
