How does a gas metering valve work?
How does a gas metering valve work?
The fuel metering valve solenoid is powered from a system relay on the positive side and the ECU switches the negative side to the ground. The fuel pressure sensor signal indicates the pressure in the fuel rail, the signal voltage increases as the fuel pressure increases.
What is an IMV valve?
The pump maintains the rail pressure by continuously delivering fuel to the common rail. One common approach is to meter the fuel drawn into the pump (inlet metering) with some type of inlet metering valve (IMV)—sometimes also referred to simply as a fuel metering valve (FMV).
Can a mprop pump be replaced without capscrews?
Not all MPROP’s are the same, they are graded (same part number) for fuel flow, and different part numbers have different flow rates. They are very easy to replace, just 3 Torx head capscrews. Hope this helpsJohn
Why does my mprop stick to my table?
You could have a sticking MPROP, they are very susceptible to scoring, this makes the MPROP unresponsive at first, because it requires more current to move it than the ECM tables deliver, eventually it may stick fast in a position, or it may live.

What is the cp4.2 inlet metering valve ( mprop )?
Learn more Exergy Performance CP4.2 Inlet metering valve (MPROP). The CP4 Pump is prone to failure if the fuel system has any water or contaminated fuel introduced to it.

How many microns are in system Saver valve?
The System Saver Valve screen is rated at 25 microns and is wrapped in two layers. This improved micron rating and double wrap construction will do a much better job of keeping debris from entering the rest of the fuel system.
