DTC codes / P22xx · Fuel and air metering (injector circuits) / P2292
P2292 means the engine computer detected an erratic signal from the fuel injector control pressure sensor, which monitors the high-pressure fuel circuit on diesel engines. The computer expects a smooth, predictable pressure reading, and an erratic signal indicates the pressure is fluctuating beyond normal limits or the sensor circuit is unreliable.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
