The diagnosis of the fuel rail pressure sensor consists of electrical checks (signal range checks):
If the measured voltage from the fuel rail pressure sensor exceeds the upper calibration limit, a short circuit to battery or cable breakage is detected and a maximum fault is set.
If the measured voltage from the fuel rail pressure sensor exceeds the lower calibration limit, a short circuit to ground is detected and a minimum fault is set.
