The pressure regulating valve performs the same function as the overpressure valve. In the event of overpressure, the valve, by opening, limits the pressure in the accumulator. If the pressure is lower than required, the valve closes and hermetically separates the low pressure section from the high pressure section of the injection system.
Valve check
Check valve resistance. Resistance: 2.07-2.53 ohms.
Valve replacement
If the valve output voltage is not correct, replace the valve. Tightening torque: 5±1 Nm.
