The suction control valve (SCV) 294200-0300 is a fuel control component used in selected Denso common rail diesel fuel injection systems. It is also known as a diesel pump suction control valve or fuel pump metering valve.
This valve is installed on the fuel inlet side of a compatible high-pressure fuel pump. It helps control the amount of fuel entering the pump, supporting the fuel pressure control process in the common rail system.
The 294200-0300 is a short-type SCV associated with selected Toyota diesel applications. Before ordering, check the original part number and high-pressure fuel pump reference to confirm compatibility.

In a common rail diesel system, the high-pressure fuel pump supplies fuel to the common rail. The engine control unit (ECU) controls the SCV according to the system design and operating conditions.
The SCV adjusts the fuel entering the high-pressure pump. This helps control the fuel supply and supports the required common rail pressure.
A properly matched SCV is important for the intended operation of the fuel injection system. However, fuel pressure problems can also be caused by the high-pressure pump, injectors, wiring, fuel contamination, or other components. Proper diagnosis is recommended before replacing the valve.
The SCV 294200-0300 is listed for selected Toyota diesel vehicles equipped with compatible Denso common rail fuel pumps.
Related applications in parts catalogs include selected models from the following ranges:
Toyota Hilux
Toyota Hiace
Toyota Land Cruiser
Toyota RAV4
Toyota Avensis
Toyota Corolla and Corolla Verso
Toyota Dyna
The exact application depends on the vehicle year, engine type, fuel pump design, and original part number. This list is for reference only and does not confirm compatibility with every model in each range.
Before purchasing a replacement SCV, check the following details:
Original SCV part number: 294200-0300
High-pressure fuel pump number
Vehicle model and production year
Engine code
Valve body length and mounting design
Electrical connector and confirmed replacement reference
Some parts catalogs list 04226-0L030 and other numbers as related references for 294200-0300. Always verify the replacement relationship against the specific fuel pump and valve design.
Do not replace a short-type SCV with a different valve design unless the application data or an approved conversion kit confirms that the replacement is suitable.
SCVs may look similar but can differ in body length, electrical characteristics, control design, and application.
Using the correct valve helps ensure that the replacement matches the fuel pump and its control system. Correct part identification also helps distributors manage inventory and reduce incorrect orders.
If a diesel engine has unstable fuel pressure or starting problems, the SCV may be one component to check. These symptoms alone do not prove that the valve is faulty, so further testing may be needed.
