Description
Product Overview
The oil pressure sensor is installed in the high-pressure common rail pipe. The probe directly contacts the high-pressure fuel and converts the real-time oil pressure into an electrical signal, which is then transmitted to the vehicle's computer. The electronic control unit regulates the fuel supply volume based on the signal. Over time, under the impact of thousands of bar of high-pressure fuel, the internal sensing chip ages, the seal leaks, resulting in oil pressure data deviations, restricted vehicle power, frequent fault code alerts, unstable idle, and excessive black smoke. This product has standardized specifications for threads, plugs, and pressure ranges. Maintenance can be carried out by directly replacing the entire unit without the need for calibration or adjustment. It is suitable for the maintenance of light trucks, agricultural machinery, and small and medium-sized excavators with common rail diesel engines.
Core advantages of this product:
The colored zinc hexagonal metal valve body is rust-resistant and does not deform under pressure.
The valve body is electroplated with colored zinc for rust prevention, protecting it from the erosion of cabin moisture and diesel oil. The thickened hexagonal main body has high pressure-bearing strength and will not crack or leak under long-term ultra-high pressure impact. It is suitable for dusty and humid working conditions in construction sites and farmlands.
The standard hexagonal clamping structure is not prone to slipping and leakage during disassembly and assembly.
The integrated hexagonal wrench has a locking mechanism, providing uniform clamping force, and during disassembly and assembly, the internal sensing core will not be twisted. The threaded assembly is tightly fitted, preventing high-pressure fuel from leaking through the installation thread gap.
The black front high-pressure sensing probe accurately collects rail pressure data.
The probe is equipped with a high-precision pressure sensing chip that is resistant to diesel impurities and can capture subtle pressure fluctuations in the oil circuit. The signal output is stable and linear, avoiding oil pressure misjudgment that leads to power limitations.
The brown rear waterproof electronic control plug isolates oil, water, and vapor short circuits.
The integrated brown sealed plug connector comes with a built-in waterproof and dustproof rubber ring, preventing diesel, rainwater from entering the connector, causing signal interruption or circuit short circuit, and suitable for long-term outdoor operation equipment.
The clear part number is laser-engraved on the hexagonal outer wall, making it easy to identify and distinguish during inventory and maintenance when matching the model.
The laser-engraved part number on the hexagonal outer wall is resistant to diesel soaking and wiping without peeling, allowing for quick identification of specifications during warehouse storage and maintenance, avoiding incorrect installation and signal mismatch faults.
The factory-standard pressure range is calibrated, and the sensor can be directly matched with the original vehicle's electronic control when installed.
Each sensor is uniformly calibrated with a standard pressure range at the factory, and the signal output parameters are unified. After replacement, there is no need to recalibrate with a computer, quickly eliminating oil pressure-related fault codes and restoring the equipment's normal power output. Applicable scenarios
It is suitable for light-duty freight trucks, agricultural tractors, small and medium-sized wheeled excavators, and fixed diesel generator sets that are equipped with high-pressure common rail fuel supply systems. It is applicable for short-distance freight transportation, agricultural operations, continuous construction work, and environments with high temperatures, vibrations, dust, and impurities and diesel fuel for electronic control common rail diesel engine oil pressure monitoring components replacement.
