P2292 — Injector Control Pressure Erratic
ICP signal is unstable or jumps — connector or sensor issue, or air in the high-pressure oil rail. A flow-deviating injector throws off cylinder balance — adjacent cylinders run leaner/richer to compensate, often masking the root cause until the trim limit is hit.
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.
