P229C

DTC P229C, sometimes indicated as P229C00 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 pressure regulator 2 exceeded learning limits - too low.

A code P229C may mean that the fuel pressure regulator 2 has exceeded the learning limits, possibly because the fuel pressure is too low. To fix this, check the fuel pressure and make sure it is within the correct range. If it is not, adjust it as necessary.
