High performance manufacturing processes include automatic data acquisition systems for continuously monitoring sensor outputs to ensure they respond with appropriate voltage output within a specified frequency range. Effectively restoring your engine and avoiding detonation or noise is crucial for high-quality durability, which is why our sensor wiring harness is designed with tin plated and solid brass terminals to ensure excellent conductivity. At the same time, high-quality materials help resist corrosion of wiring harnesses, ensuring a longer service life.
