Description
Product Overview
The pressure sensor is threadedly locked at the oil passage point of the high-pressure common rail pipe. The internal high-precision sensing chip continuously captures the changes in fuel pressure and converts them into voltage signals that can be recognized by the electronic control system. The electronic control unit dynamically adjusts the oil pump's supply volume and the timing of fuel injection based on these signals. Under long-term conditions of thousands of bar of high-pressure fuel, continuous flushing, alternating cold and hot vibrations in the engine compartment, and corrosion from diesel and oil, the internal sensing elements age and the assembly seal fails, resulting in drift in rail pressure data, power output discontinuities, rapid pressure relief after engine shutdown, and difficulty in starting. This product has standardized processing for its thread specifications, signal output range, and pressure-bearing threshold. Repairing the abnormal oil pressure signal fault only requires replacing the sensor separately. It is suitable for the maintenance of electric control common rail diesel engines for light pickup trucks, light trucks, and small passenger diesel vehicles.
Core advantages of this product:
Segmented composite metal pressure-bearing shell, resistant to high pressure, rust prevention, and corrosion resistance
The black high-strength threaded section at the front is combined with the middle section of the mirror-finish stainless steel pressure-bearing cylinder. The double-layer structure can withstand continuous ultra-high oil pressure impact, isolating the engine compartment from water vapor and diesel-oil corrosion, providing long-term protection for the internal sensing chip from medium damage.
The extended standard external thread is suitable for multiple specifications of common rail pipe installation holes.
The front end has an extended rolled external thread with regular tooth shape and precise clearance, which is compatible with various models of common rail pipe installation bases. It is equipped with an internal sealing gasket, and after tightening, it completely seals the oil passage gap, preventing high-pressure fuel leakage and pressure relief.
The middle section has a double hexagonal clamping structure, making disassembly and assembly less prone to slipping or deformation.
There are six-agon limiters at both the front and rear, compatible with both the socket and open-end wrench tools. The force distribution during disassembly and assembly is uniform, preventing the internal precision sensing components from being compressed, avoiding shell distortion, and preventing thread slippage, thus avoiding leakage faults.
The side-mounted split waterproof electronic control plug is stable in signal transmission and resistant to interference.
The black multi-pin sealed connector has a built-in dustproof and waterproof rubber gasket, isolating the engine compartment from oil stains, water vapor, and dust, preventing short circuits and loss of oil pressure signals. The signal transmission is without delay or drift under high-load conditions.
A metal auxiliary assembly pin is provided, facilitating assembly in a narrow space.
An integrated metal auxiliary pin is included, specifically for the narrow engine compartment operation space. It assists in tightening and disassembling the sensor, reducing the difficulty of maintenance and assembly, and improving maintenance efficiency.
The oil pressure signal calibration is performed during factory assembly, eliminating the need for secondary adjustment.
Each sensor is independently calibrated for the oil pressure-voltage corresponding curve. The factory signal parameters are uniform, and after assembly, it directly matches the original vehicle's electronic control system, quickly restoring the vehicle's stable power output.
