Dongfeng GX post-processing at both ends Differential pressure sensor assembly 3615610-TL100

Engineered exclusively for Dongfeng GX’s post-processing setup, this assembly matches OEM dimensions with ±0.1mm tolerance, ensuring perfect alignment with the system’s pressure ports. The dual-end connectors (1/4-inch NPT threads) fit exactly into the DPF/SCR inlet and outlet ports, creating a leak-tight seal without adapters. The electrical connector (6-pin) is identical to the factory part, plugging directly into the Dongfeng GX’s wiring harness—no splicing or reconfiguration needed. Unlike generic sensors, it follows the post-processing system’s original layout, avoiding interference with nearby components (e.g., urea lines, exhaust pipes). Rigorously tested on Dongfeng GX test vehicles, it passes 180+ fitment checks to guarantee consistency. For repair shops and owners, this means a hassle-free replacement that maintains emissions compliance and avoids system malfunctions from misfit parts

Built to endure the extreme conditions of vehicle post-processing systems, the assembly uses rugged, resistant materials. The sensor body is made of high-temperature PPS (polyphenylene sulfide) plastic, capable of withstanding continuous exposure to 150°C (peak 200°C) without deformation. The diaphragm uses Hastelloy C-276, a corrosion-resistant alloy that resists damage from exhaust gases, urea, and cleaning agents. The seal rings are made of FKM (fluorocarbon rubber), ensuring chemical stability and maintaining a tight seal even under thermal expansion. It passes 500 hours of high-temperature aging tests (150°C) and 300 hours of chemical immersion tests (urea solution), ensuring no performance degradation. For owners, this durability means reliable operation in long-term use, reducing the need for frequent sensor replacements and avoiding emissions-related warning lights

The 3615610-TL100 assembly is critical for Dongfeng GX’s compliance with global emissions regulations (e.g., Euro 6, China VI). It provides the ECU with accurate DP data to optimize the post-processing system, ensuring emissions of NOx and particulate matter stay within legal limits. The sensor complies with ISO 15001 (automotive electronics environmental standards) and ECE R10 (electromagnetic compatibility), avoiding interference with the vehicle’s other electronic systems (e.g., engine control, ABS). Each unit undergoes rigorous certification tests: pressure cycle testing (10,000 cycles of -10kPa to +10kPa), temperature cycle testing (-40°C to 150°C), and EMC testing (radiated immunity up to 200V/m). It also carries Dongfeng’s official quality certification, ensuring consistency with the brand’s emissions control benchmarks. For owners, this compliance prevents fines from regulatory authorities and ensures the vehicle passes emissions inspections

Designed for easy installation, the assembly requires no specialized tools or calibration, making it accessible to professionals and DIY owners. The process takes 25 minutes max: 1) Disconnect the vehicle’s battery to ensure safety; 2) Unplug the 6-pin electrical connector from the old sensor; 3) Use a 19mm wrench to loosen the old sensor’s dual-end NPT connections from the post-processing ports; 4) Apply a thin layer of high-temperature thread sealant (included) to the new sensor’s threads; 5) Tighten the new sensor to the specified torque (25±2 N·m) and reconnect the electrical connector. No ECU reprogramming is needed— the sensor auto-syncs with Dongfeng GX’s system once powered on. A detailed instruction manual with torque specs and safety notes is included. This saves time and labor costs, avoiding expensive dealer visits and ensuring the post-processing system resumes normal operation quickly
