Fuel Pressure Sensor 202V27421-0263 Sinotruk Sitrak

Product Introduction

This Fuel Pressure Sensor 202V27421-0263 is an OEM core monitoring component for the common rail fuel system of heavy-duty diesel engines (e.g., Sinotruk Howo, Weichai WP series). It features a precision-machined stainless steel sensing body with standard metric threads, a high-sealing black waterproof electrical connector, and laser-engraved part number identification. Engineered to accurately monitor the real-time fuel pressure in the common rail, it is manufactured in strict accordance with OEM standards to ensure stable signal output under extreme conditions of high vibration, temperature fluctuations, and fuel pressure changes in commercial vehicle operation.

Core Function

1. Precision Fuel Pressure Monitoring: Accurately detects the pressure value of the engine’s common rail fuel system and transmits real-time analog or digital signals to the ECU.

2. Engine Performance Optimization: Provides critical input for the ECU to adjust fuel injection quantity and timing, ensuring optimal combustion efficiency, power output, and emissions control.

3. System Protection: Triggers protective measures if fuel pressure exceeds or falls below safe thresholds, preventing damage to the fuel injectors, high-pressure pump, and other fuel system components.

4. Durable Sealing Performance: The integrated high-temperature resistant rubber sealing ring and precision thread fit ensure zero fuel leakage; the fully sealed connector effectively prevents moisture and dust from entering the internal circuit.

5. OEM Plug-and-Play Compatibility: Strictly follows the original engine’s thread size, pin definition, and mounting torque requirements, achieving 100% interchangeability with the original sensor, and supporting direct replacement without calibration.
