P2030
Fuel Fired Heater Performance
DTC P2030, sometimes indicated as P203000 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing fuel fired heater performance.
This trouble code is caused by a problem with the fuel fired heater. Possible causes include a bad fuel pump, a clogged fuel filter, or a defective fuel valve. If the fuel fired heater is not working properly, it will not be able to heat the engine coolant to the correct temperature, which will cause the engine to overheat.
One possible solution is to replace the fuel fired heater. If the problem is caused by a bad fuel pump or a clogged fuel filter, those parts may also need to be replaced.
