What does code P2290 mean?

Q: What does code P2290 mean?

Injector Control Pressure Too Low. P2290 means the engine computer has detected that the fuel injector control pressure is lower than the expected value for the current operating conditions. On diesel engines with a high-pressure oil-driven injection system, this typically indicates a loss of actuation oil pressure or a faulty pressure sensor circuit.
