What does code P2285 mean?

Q: What does code P2285 mean?

Injector Control Pressure Sensor Circuit Low. P2285 means the powertrain control module (PCM) has detected a low voltage signal from the injector control pressure (ICP) sensor circuit, which typically monitors fuel rail pressure on diesel engines. The PCM expects a voltage within a calibrated range that rises with pressure, and a sustained low reading tells it the sensor signal is below the minimum threshold or shorted to ground.
