Hella 009309541 Engine Coolant Temperature Sensor

The Hella 009309541 is a precision-engineered engine coolant temperature sensor designed to monitor and report your engine's operating temperature to the vehicle's computer system. This critical component plays a vital role in engine performance by allowing the ECU to adjust fuel injection and ignition timing based on real-time temperature data.

Key Features:

• OE-quality temperature sensor with NTC (Negative Temperature Coefficient) technology for accurate readings
• 2-pin electrical connector design for reliable signal transmission
• 12-volt compatible system integration
• Radiator-mounted location for optimal coolant temperature monitoring
• Plugged design with integrated seal to prevent coolant leaks
• Direct replacement for OEM sensors on BMW, Land Rover, and Mini applications

Manufactured by Hella, a trusted name in automotive electronics and sensors, this coolant temperature sensor delivers the precision and durability required for proper engine management. The sensor uses temperature-dependent resistance technology, providing high impedance when the engine is cold and low impedance when hot, allowing the engine control unit to optimize performance across all operating conditions.

A properly functioning coolant temperature sensor is essential for maintaining fuel efficiency, reducing emissions, and preventing engine overheating warnings. This genuine Hella sensor provides direct fitment and reliable operation for long-term performance.
