Professional Team
Currently, we have over 80 employees, including 6 experienced technical engineers and 8 professional technical and inspection personnel, providing strong support for product development and quality control.

Key Advantages
Direct OEM fit and function – the connector, mounting holes, and shaft alignment match the factory specifications exactly. Bolt it on and plug it in—no modifications or calibration required.

High-quality components for reliability – the internal potentiometer uses a long-life conductive plastic track, tested to withstand 1 million cycles without significant wear. The housing is constructed from glass-filled PBT, resistant to underhood heat and chemicals.

Rigorous quality control – each TPS sensor is 100% inspected before shipping, not batch-sampled. Every unit passes resistance sweep tests at both room temperature and extreme conditions to confirm stable output.

Q1: Is this F4SZ9B989AA / ESB989AA throttle position sensor a direct replacement for my vehicle?
Yes. It is designed with OEM-style fit and function, matching the original connector, mounting points, and shaft alignment for compatible Mazda, Ford, and Mercury applications.

Q2: How does this TPS sensor help maintain engine performance?
It detects throttle opening changes and sends accurate signals to the ECU, helping control fuel injection, ignition timing, and overall engine response.

Q3: How durable is this throttle position sensor for long-term use?
The sensor uses a long-life conductive plastic potentiometer tested for up to 1 million cycles, with a glass-filled PBT housing designed to resist heat and chemicals.

Q4: How does the manufacturer ensure product quality before shipment?
Each TPS sensor is 100% inspected and tested, including resistance sweep tests under normal and extreme conditions, to ensure stable output and reliable performance.

Q5: Can the supplier support customized orders or long-term cooperation?
Yes. With certified quality systems, advanced production equipment, and professional engineering support, the supplier can provide customized solutions and stable supply for different customer needs.
