OEM Common Rail Fuel Pressure Sensor ME229553 0281006086 For Mitsubishi Fuso Canter 4M50 Euro-3 — 1800 Bar M18x1.5 3-Pin Rail Sensor

The Common Rail Fuel Pressure Sensor with OEM number ME229553 (also listed as ME 229553, 0281006086, 0 281 006 086, 0281002841) is a verified OEM-grade direct replacement for Mitsubishi Fuso Canter trucks equipped with the 4M50 4.9L diesel engine in Euro-3 configuration.

If your rail pressure sensor is failing, you may experience one or more of the following symptoms:

• Sudden Power Loss: The engine experiences abrupt drop in power, especially under load or when climbing hills
• Black Smoke from Exhaust: Excess fuel injection caused by incorrect rail pressure readings results in incomplete combustion and heavy black smoke
• Rough Idle or Shaking on Startup: Engine idles unevenly or shakes violently on cold start — indicates unstable rail pressure control
• Hard Starting / Extended Cranking: Difficulty starting the engine due to incorrect fuel pressure readings during cranking
• Diagnostic Trouble Codes (DTCs): Codes such as P0087 (Rail Pressure Too Low), P0088 (Rail Pressure Too High), or P0191 (Fuel Rail Pressure Sensor Circuit Range/Performance)
• Limp Mode / Engine Derate: The ECU detects an implausible rail pressure signal and limits engine power to protect the fuel system

• Depressurize the fuel system before starting work
• Disconnect the negative battery terminal
• CRITICAL: The common rail fuel system is highly sensitive to contaminated or poor-quality diesel fuel — always use clean, high-quality fuel and replace the fuel filter simultaneously
• Clean the area around the sensor and fuel rail to prevent contamination
• Quantity Required: 1 sensor per engine

1. Depressurize the fuel system and disconnect the negative battery terminal
2. Locate the rail pressure sensor on the fuel rail
3. Disconnect the 3-pin electrical connector from the sensor
4. Remove the sensor using an M18 deep socket
5. Clean the mounting port and sensor seat thoroughly
6. CRITICAL: Install the new sensor with a new copper sealing washer (if applicable)
7. CRITICAL: Torque the sensor to manufacturer's specified torque settings (refer to Mitsubishi Fuso workshop manual)
8. Reconnect the electrical connector until it clicks
9. Reconnect the battery and prime the fuel system
10. CRITICAL: Bleed air from the fuel system thoroughly to remove all air
11. Start the engine and check for fuel leaks around the sensor
12. Clear any diagnostic trouble codes using a scan tool

• Inspection: Every 50,000 km / 12 months. Check for fuel leaks, power loss, or increased fuel consumption
• Fuel Filter Replacement: Every 20,000-30,000 km — regular filter changes are the single biggest factor in fuel system longevity
• Replacement: Recommended at 150,000-200,000 km or immediately if failure symptoms appear
• Note: The rail pressure sensor is a critical component of the common rail fuel system — proactive replacement is recommended during major fuel system service

• Packaging: Each sensor is securely packed in a neutral box, color box, or customer brand package
• Pack Quantity: 1 PC
• Net Weight: Approx. 0.07 kg
• Warranty: 12 Months
• Suitable for: Wholesale distributors, truck parts retailers, commercial vehicle repair shops, construction equipment service centers, and fleet owners
