Dual Differential Pressure Sensor OE K179470 for Dongfeng GX & KX Heavy Tractors

This genuine dual differential pressure sensor with OE number K179470 is factory original aftertreatment electronic component exclusively matched for Dongfeng GX and KX heavy-duty trucks. It features dual independent pressure sampling ports to measure exhaust pressure difference before and after DPF, sending real-time electrical signals to vehicle ECU to control EGR and SCR emission systems. The shell adopts high-strength anti-corrosion PA66 plastic with full epoxy encapsulation for waterproof, dustproof and anti-high-temperature performance. Dual silicone pressure inlet nipples prevent gas leakage, and the standard 3-pin waterproof plug matches original vehicle wiring harness for direct bolt-on installation. This differential pressure sensor strictly passes DFCV OEM alternating pressure cycle test, -40℃~+125℃ high-low temperature aging test and vibration fatigue test. Authorized third-party automotive electronic inspection verifies mounting hole spacing, signal protocol and air channel parameters fully consistent with factory original assemblies, widely used as replacement spare parts for DPF blockage alarms, emission fault lights and sensor signal loss on Dongfeng GX & KX long-haul fleets.

PRODUCT DESCRIPTION

Dual Independent Sampling Ports, Fully Epoxy Sealed, High Temp Resistant Housing

This OE K179470 dual pressure sensor equips two separate pressure inlet nipples to synchronously collect upstream and downstream DPF exhaust pressure data, supporting accurate differential pressure calculation for truck aftertreatment systems. The whole internal circuit board adopts full epoxy encapsulation technology to isolate exhaust gas, water vapor and road dust, avoiding short circuit and signal drift under harsh engine compartment environments. High temperature resistant engineering plastic shell resists long-term heat radiation from exhaust pipelines. Double mounting holes, air nozzle spacing and electrical plug pin definition fully comply with Dongfeng GX & KX original cab exhaust system design. No wiring conversion or bracket modification needed during replacement. Stable signal output effectively prevents false DPF clogging fault alerts and abnormal emission system derating.

Single Channel Signal Deviation, Water/Gas Intrusion Trigger MIL Lamp, High Temp Aging Failure

Heavy truck maintenance technicians often encounter typical defects of inferior aftermarket differential pressure sensors: single weak sampling channel causes inaccurate pressure difference calculation; incomplete sealing lets exhaust condensate and dust damage internal chips; low-grade plastic shell deforms at high temperature leading to sensor failure. This genuine DFCV OEM dual pressure sensor eliminates these hidden risks: dual balanced sampling channels ensure precise data feedback; fully sealed structure blocks liquid and particle intrusion, lowering exhaust aftertreatment overhaul frequency for Dongfeng GX & KX logistics fleets.

DFCV OEM GX/KX Aftertreatment Standard, Multi-Round Vibration & Wide Temp Lab Testing

As core exhaust monitoring electronic spare part of Dongfeng GX & KX heavy truck SCR/DPF aftertreatment system, this dual differential pressure sensor fully complies with Dongfeng Commercial Vehicle official heavy-duty vehicle emission component production quality standards. Every finished sensor completes three mandatory durability laboratory tests: thousands of times alternating pressure cycle simulation test, long-time high-low temperature alternating aging test, road bump vibration fatigue test, maintaining stable signal performance under plateau, high-temperature summer and muddy mountain transportation environments. Unique QR traceability code and OEM part number marking are molded on sensor housing for genuine product verification. All shell outline, mounting hole layout and air nozzle dimension strictly follow factory engineering drawings, zero assembly mismatch after replacement for all matching Dongfeng GX and KX heavy truck models.

In-Stock Genuine OEM Dual Pressure Sensors & Fast Low-Downtime Emission Repair Wholesale Supply

We are authorized Dongfeng wholesale supplier of genuine DFCV OEM exhaust aftertreatment spare parts for Dongfeng GX & KX heavy trucks, maintaining permanent sufficient stock of OE K179470 dual differential pressure sensors. Each sensor is sealed with anti-static plastic bag and shockproof export carton packaging to prevent air nozzle deformation, circuit board collision and plug scratch during cross-border sea and land logistics transit. Its pre-calibrated mounting hole spacing and standard waterproof plug allow professional heavy truck maintenance technicians to finish sensor replacement within 10 minutes without refitting exhaust pipeline brackets or modifying wiring, drastically cutting vehicle power-limit downtime for long-haul logistics fleets and truck emission fault repair garages. We provide a 12-month stable signal transmission quality warranty plus free remote exhaust pipeline matching installation guidance for all worldwide bulk wholesale buyers.

TECHNICAL SUPPORT

1. Accessories selection consultation

- Provide ** intelligent selection tools ** (such as parts matching query system), input the vehicle model VIN code or engine model to match the corresponding parts number, reducing the selection error rate.

The technical team is available online 7×12 hours to answer technical questions about accessories (such as material compatibility and installation processes).

2. Customized development support

We offer specialized R&D services for special market demands (such as heat dissipation accessories for high-temperature regions in the Middle East and dedicated suspension components for road conditions in Africa), and complete sample delivery within six weeks.

3. Training and Technical materials

Provide remote/on-site training for the customer's after-sales team (such as diagnosis of electrical control accessories and DPF regeneration operation), along with multilingual versions of the "Accessories Installation Manual" and "Troubleshooting Guide".

4. Quality Traceability and Improvement

Through the QR code traceability system (one product, one code), track the production batch of accessories and the source of raw materials, respond quickly to quality complaints and initiate improvement processes.

AFTER-SALES AND LOGISTICS SUPPORT

After-sales service

Quality Assurance Policy

-The warranty period for original factory parts is 12 months (counting from the date of signature for receipt), covering material defects, process issues, and man-made damage.
