CRD (Bosch) fuel rail pressure sensor - voltage

The rail pressure sensor is calibrated to output a signal between V and V with changing rail pressure across the range 0 bar to 1600 bar. This provides two opportunities for the ECM to undertake a signal plausibility check: any voltage above or below these values, for example, either at 0 V or 5 V, will indicate that the sensor has failed.
