Show original supplier description
The Continental SE1004S is a flex fuel sensor engineered for accurate ethanol content measurement in E85 and flex fuel applications. This sensor is installed in the fuel line, typically between the fuel tank and injectors, and transmits its output signal to the vehicle's engine control unit (ECU). By providing precise data on the actual percentage of alcohol in the fuel, the ECU can dynamically adjust injection rates and ignition timing for optimal engine performance and efficiency. Constructed with a combination of plastic and metal, this sensor features male blade terminals, with three terminals in total, and operates on a 12-volt system. This ensures a high level of quality and reliability, making it suitable for both professional technicians and DIY enthusiasts seeking ease of installation and dependable performance. As an OE component, the Continental Flex Fuel Sensor provides the genuine quality expected by auto manufacturers. Its function is critical for vehicles designed to run on various fuel blends, including E85, as it allows the engine management system to adapt to different fuel compositions. This adaptability is key to maintaining engine health, maximizing fuel economy, and achieving optimal power output across a range of fuel types.
