BRAND NEW OEM Quality FUEL RAIL PRESSURE SENSOR / REGULATOR TO SUIT HYUNDAI 2.5L D4CB Diesel Engines (ILOAD IMAX).
Replaces both 56mm and 60mm OE Sensors

IMPORTANT FITMENT CHECK

CRITICAL MOUNTING LOCATION: Please check your engine bay before ordering. This specific sensor mounts on the END of the fuel rail. If your original sensor mounts on TOP of the fuel rail you require the RPS109 variant instead. Verify your OEM part number is 85PP30-02 or 31400-4A700.

PACKAGE INCLUDES:

1 X OEM Quality FUEL RAIL PRESSURE SENSOR. (3-PIN PLUG. D-Shaped Connector)

Sensor fits in End of Fuel Rail - Check the illustration for the correct connector plug

A fuel rail pressure sensor is a component in a vehicle's fuel system that measures and monitors the fuel pressure in the fuel rail, a pipe or tube that delivers fuel to the fuel injectors. This sensor is an essential part of modern fuel injection systems commonly found in gasoline and diesel engines. Its primary purpose is to provide crucial data to the engine control unit (ECU) or engine control module (ECM) so that the engine can operate efficiently and safely.

Our Fuel Pressure Regulators are:

Application specific for the perfect fit and form
Direct-fit OE replacement ensures proper fit, form, and function, which leads to a trouble-free installation
Premium components and durable materials withstand harsh engine conditions to resist leaks
Designed and manufactured to stringent quality standards at a certified facility, so you can install with confidence
Undergoes extensive testing and validation for proper performance and peak reliability

COMMON QUESTIONS

How do I know if I need the End Mount or Top Mount sensor?

Hyundai used two different fuel rail designs on the 2.5L D4CB engine. You must visually inspect your engine. If the sensor is screwed into the very end of the rail tube you need this part (RPS115). If it is screwed into the top face of the rail you need the RPS109 variant.

What are the symptoms of a failing D4CB fuel rail pressure sensor?

A faulty sensor sends incorrect fuel pressure readings to the ECU. This often results in a Check Engine Light rough idling a severe lack of power limp mode and the engine randomly stalling while driving.

Do I need to program this sensor after installation?

No programming is required for this direct replacement sensor. However you must use an OBD2 scanner to clear any stored engine fault codes before starting the vehicle so the ECU can learn the new pressure readings.

Please Note: Suitable for Diesel Rail only. Sensor fits in End of Fuel Rail - Check Illustration for correct connector plug

There are either of two types of rails connected to these engines and sensors are different for the rails.

This listing is for a D-shaped Sensor connected at the end of the rail (Not the top of the rail). check the part number on your original rail.

The correct number for OEM rail is 31400-4A700

What is the difference between a fuel rail pressure sensor and a fuel pressure regulator?

The fuel rail pressure sensor is an electronic sensor that monitors fuel pressure in the rail and reports this data to the ECU in real time. The ECU uses the sensor reading to adjust injector pulse width and pump output. The fuel pressure regulator is a mechanical or electronic valve that physically controls and limits fuel pressure by diverting excess fuel. They work together - the regulator sets the pressure and the sensor monitors it.

What are the symptoms of a faulty fuel rail pressure sensor?

A faulty fuel rail pressure sensor sends incorrect pressure data to the ECU, causing it to miscalculate fuel delivery. Common symptoms include hard starting, engine stalling at idle or under load, poor fuel economy, hesitation under acceleration, engine entering limp mode on diesel vehicles, and a Check Engine light with fuel pressure codes P0190 to P0194. On common rail diesel engines the symptoms can be severe as rail pressure management is critical.

What are the symptoms of a faulty fuel pressure regulator?

A failing regulator causes persistent fuel pressure problems. A regulator that allows pressure to rise too high causes the engine to run rich, producing black smoke, high fuel consumption, and fuel smell from the engine bay. A regulator that allows pressure to drop too low causes hard starting, stalling, hesitation, and loss of power under load. Both conditions affect injector performance and can cause misfires and catalyst damage over time.

Can I drive with a faulty fuel rail pressure sensor or regulator?

You can drive short distances but it is not recommended. A faulty pressure sensor may cause the engine to run incorrectly rich or lean depending on the failure mode. A faulty regulator causing low pressure can leave the vehicle stranded if pressure drops below the minimum required for starting. Continued driving with a fuel pressure fault can also damage fuel injectors and catalytic converters.

How do I know if my fuel pressure problem is the sensor or the regulator?

A faulty sensor will produce incorrect ECU readings without affecting actual fuel pressure - you can verify this by checking actual fuel pressure with a mechanical fuel pressure gauge while the engine is running. If the mechanical gauge reads correctly but the ECU is reporting an incorrect value, the sensor has failed. If the mechanical gauge also reads incorrectly, the fault is in the regulator, pump, or fuel system rather than the sensor.

Do fuel pressure sensors and regulators need programming after replacement?

No programming is required for either component. Both are direct replacement parts that plug directly in. Clear stored fault codes with an OBD2 scanner after replacement and verify the fuel pressure reading in live data matches the specification for your engine. On common rail diesel engines allow several minutes of running time for the system to stabilise before checking live data values.
