P2290 — Injector Control Pressure Too Low
ICP is below the lower threshold — typically IPR stuck open, leaking high-pressure oil rail, or weak HP oil pump.
General code reference. Confirm the definition and diagnostic procedure for your vehicle's year, model and engine. A stored code alone does not identify a failed part.
