Introduction

621600090771 oil pressure sensor is a professional high-precision electronic sensing part exclusively designed for SINOTRUCK heavy-duty trucks, fully compatible with SINOTRUCK HOWO, Sitrak, Shantui and supporting Weichai engine series. As a key component of the engine lubrication monitoring system, it real-timely detects the engine internal oil pressure data, converts physical pressure signals into electronic signals, and feeds accurate data back to the vehicle ECU and dashboard. It effectively monitors the normal operation of engine lubrication system, timely feeding back abnormal oil pressure conditions such as low pressure, high pressure and oil shortage. Manufactured strictly in accordance with OEM standard specifications, it features sensitive induction, stable signal transmission and strong environmental adaptability, serving as a perfect direct replacement for original damaged, failed and aging sensors for heavy truck maintenance and overhaul.

Key Features

✅️Standard OEM Matching & Wide Compatibility      

Adopting standard OEM part number 621600090771, this sensor completely matches the original installation size, thread specification and wiring interface. It is widely applicable to SINOTRUCK full-series heavy trucks and matching Weichai engines, realizing plug-and-play installation without modification. The precise docking structure ensures zero assembly deviation, perfectly adapting to original vehicle circuit and monitoring system.

✅️High-Precision Sensing & Accurate Signal Feedback      

Built-in high-sensitivity precision sensing chip with stable induction performance, the sensor can accurately monitor real-time engine oil pressure changes within the standard working range. It delivers accurate and stable signal output without delay, distortion or signal drift. It effectively avoids false alarms and missing alarms, ensures the driver can accurately grasp the engine lubrication status, and guarantees safe vehicle operation.

✅️Excellent High Temperature & Vibration Resistance      

Designed with professional industrial-grade high-temperature resistant shell and internal electronic components, it can adapt to the high-temperature and high-vibration harsh working environment of truck engine cabins. It maintains stable sensing performance under long-term engine operation and bumpy road driving, avoiding sensor failure and signal interruption caused by high temperature and vibration.

✅️Superior Sealing & Dust-Proof Waterproof Performance      

Adopting integral injection molding and multi-layer sealing process, the product features tight overall sealing performance. It effectively isolates external dust, rainwater, oil stain and sediment, prevents internal circuit oxidation, short circuit and water ingress damage, and adapts to various complex and harsh truck working scenarios with strong environmental adaptability.

✅️Stable Performance & Low Failure Rate      

Optimized internal circuit design effectively resists electromagnetic interference from vehicle electrical system, ensuring stable signal transmission without fluctuation. All finished products undergo strict pressure sensing test, signal stability test and aging test before delivery. It solves common faults of inferior sensors such as inaccurate data, frequent alarm and easy burnout, with ultra-low long-term failure rate.

✅️Durable & Long Service Life      

Adopting high-quality anti-aging electronic components and corrosion-resistant metal thread base, the sensor has excellent anti-corrosion, anti-oxidation and anti-fatigue properties. It can maintain long-term stable working performance after thousands of working cycles, extend service life greatly, and reduce repeated replacement and maintenance costs for fleets and repair shops.

✅️Cost-Effective Factory Direct Supply      

Produced in strict accordance with OEM quality standards, the product has consistent performance with original parts, with more competitive wholesale prices. Sufficient stock, neutral packaging and fast global delivery are available. It is a high-cost-performance replacement part for global auto parts distributors, maintenance factories and logistics fleet enterprises.
