P2289

DTC P2289, sometimes indicated as P228900 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 injector control pressure too high - engine off.

The DTC P2289 code is set when the injector control pressure is too high. This code can be caused by a number of issues, including a defective injector, a leaking injector, or a defective fuel pump.
If you have this code, the first step is to determine the source of the problem. Once the source is identified, the appropriate repairs should be made. If the problem is a defective injector, for example, the injector will need to be replaced. If the problem is a leaking injector, the injector will need to be resealed or replaced. If the problem is a defective fuel pump, the fuel pump will need to be replaced.
