Modern Engine Crankshaft Position (CKP) sensors require nanosecond accuracy to ensure optimal ignition timing and fuel injection. We utilize advanced Hall-effect and Variable Reluctance (VR) technologies to provide stable signals under extreme thermal conditions.
Our sensors are encased in high-grade, heat-resistant polymers and feature rare-earth magnetic cores. This ensures resistance to engine oil, vibration, and EMI (Electromagnetic Interference), significantly extending the service life in harsh environments.
As a leading exporter, Wenzhou Sedo Auto integrates a robust supply chain that guarantees raw material availability and logistics efficiency for Tier 1 automotive distributors across Europe, North America, and Asia.

Founded in 2008, Wenzhou Sedo Auto Co., Ltd. has grown into a leading enterprise in the automotive parts industry, supported by a highly skilled production and sales team. The company integrates research & development, manufacturing, and sales, specializing in the production of high-quality automotive pumps and a wide range of automotive accessories. By continuously introducing advanced production equipment and modern management systems, we ensure that our products are innovative, durable, and meet the highest industry standards.
Guided by the business philosophy of "Credit First, Customer First, Quality Satisfaction, On-Time Delivery", we focus on understanding customer needs, promoting environmentally friendly production, continuously improving product quality, and optimizing production processes. We have established a comprehensive management system to provide our clients with professional, all-round services and long-term support.
Our manufacturing facility in Wenzhou utilizes state-of-the-art CNC machining and rigorous testing protocols to ensure every engine crankshaft position sensor exceeds OEM expectations.
The automotive industry is shifting toward electrification and advanced powertrain management. Crankshaft sensors are no longer simple tachometers; they are critical components for misfire detection, cylinder identification, and stop-start system efficiency. Our R&D team works closely with clients to provide customized solutions that meet diverse market demands, including high-frequency signal processing for high-performance engines.
In addition to business excellence, we are committed to corporate social responsibility, actively participating in community development and promoting sustainable manufacturing practices. Looking ahead, Wenzhou Sedo Auto Co., Ltd. aims to strengthen global partnerships, drive innovation in the automotive industry, and create long-term value for customers and society alike.
We provide comprehensive documentation including PPAP (Production Part Approval Process) to ensure our sensors meet regional regulatory requirements such as REACH and RoHS. Our localized support teams in major hubs ensure that technical hurdles are addressed in real-time.
Whether you require a specific connector type, wire length, or air-gap tolerance, our engineering department utilizes CAD/CAM and 3D prototyping to accelerate the development cycle of custom CKP sensors.
Testing includes thermal cycling from -40°C to +150°C and salt spray resistance. Our "Zero-Defect" philosophy ensures that every sensor shipped is capable of withstanding the lifecycle of the vehicle.
Common symptoms include engine stalling, difficulty starting (long crank times), intermittent misfires, and reduced fuel economy. A faulty sensor may also trigger a Check Engine Light with P0335 or P0336 OBD-II codes. Our OEM-quality sensors are designed to eliminate these issues with superior signal reliability.
We utilize CNC Machining Centers and specialized Grinding/Drilling machines to maintain tolerances within microns. Every sensor undergoes an automated magnetic field test and signal consistency check before packaging.
Yes, while CKP sensors are traditional to ICE (Internal Combustion Engines), we are expanding our R&D into rotor position sensors and speed sensors for electric and hybrid motors, leveraging our decade of expertise in magnetic sensing.
Standard OEM replacement orders are fulfilled within 4-6 weeks, while fully customized ODM projects take approximately 8-12 weeks from prototype approval to mass production, depending on complexity.
