This metering unit uses pulse-width modulation at 1 KHz to precisely control fuel pressure, and also functions as a mechanical pressure damper to smooth high-frequency pressure pulses from the fuel pump. Common symptoms of a failing pressure regulator include engine misfires, poor acceleration, rough idling, stalling, and reduced fuel efficiency. Installing this Bosch replacement part restores proper fuel system function and helps prevent costly engine damage.
