In the rapidly evolving landscape of automotive electronics, the Throttle Position Sensor (TPS) remains a cornerstone of the Internal Combustion Engine (ICE) and hybrid powertrains. Founded in 2008, Wenzhou Sedo Auto Co., Ltd. has established itself as a premier destination for global procurement officers seeking high-reliability OEM and ODM solutions.
With over 15 years of manufacturing experience, our facility integrates advanced R&D with stringent quality control, adhering to international standards to ensure every sensor provides precise data to the ECU.
Our R&D team works closely with global clients to provide customized solutions, from material selection to electrical output calibration, meeting diverse market demands and harsh environment requirements.
Based in the heart of China's automotive hub, we leverage localized supply chain advantages to offer competitive pricing without compromising the technical integrity required by Tier 1 distributors.
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, and optimizing production processes to provide long-term support for our global partners.
Modern automotive sensing has shifted towards Contactless Hall Effect technology. Unlike traditional potentiometers, Hall Effect sensors eliminate physical wear, significantly increasing the sensor's lifespan and reliability in high-vibration engine environments. As a leading exporter, we provide both technologies to satisfy legacy vehicle repairs and modern vehicle manufacturing.
The transition to Electronic Throttle Control (ETC) has made the TPS more critical than ever. In a DBW system, the TPS provides the primary feedback loop to the ECU. Our sensors are designed with redundancy—dual signal outputs—to ensure safety and fail-safe operation in accordance with ISO 26262 functional safety standards.
Engine bays are brutal environments. Our OEM sensors utilize high-grade thermoplastics and specialized potting compounds to resist thermal cycling (from -40°C to +150°C), moisture ingress (IP67 rating), and chemical exposure from oils and coolants.
Quality is not inspected into the product; it is manufactured into it. Our facility at Wenzhou Sedo Auto Co., Ltd. is equipped with the latest CNC and automated assembly lines to guarantee consistency across millions of units.
Maintaining tolerances within microns to ensure perfectly smooth sensor rotation and signal accuracy.
Optimized for internal sensor housing structures that require complex cooling or mounting paths.
Advanced multi-axis centers allow us to prototype and manufacture complex OEM designs with rapid turnaround times.
By consolidating manufacturing of varied components—from Valve Covers to Brake Pads and TPS Sensors—we reduce logistical complexity for international buyers.
We provide comprehensive technical documentation, 3D CAD models, and performance data sheets to support your engineering department's validation process.
Our commitment to corporate social responsibility includes energy-efficient manufacturing and the use of recyclable materials wherever technically feasible.
Typically, for standard OEM models, the lead time is 15-30 days. For custom ODM projects involving new mold development, the timeline varies from 45 to 60 days depending on complexity.
We calibrate our sensors according to the specific voltage-to-angle maps provided by the client. We conduct extensive testing using simulate ECU environments to ensure linear signal output and zero latency.
Yes, Wenzhou Sedo supports flexible manufacturing. Our CNC machining centers allow us to produce high-quality prototypes for testing before scaling up to mass production.
Our production facilities follow IATF 16949 quality management standards, ensuring that every throttle position sensor meets the rigorous demands of the global automotive aftermarket and OE sector.
We offer a standard 12-24 month warranty on all electronic components. Our technical team is available 24/7 to assist with installation guidance or troubleshooting.
