Detailed Description of the Hella 009109131 Sensor

This air charge temperature sensor from Hella uses an NTC sensor type, which means its resistance decreases as temperature increases, allowing the engine control unit to adjust fuel injection and ignition timing accordingly. The green housing provides a visual cue for technicians during maintenance or replacement. The plugged mounting type ensures a secure fit within the intake system, minimizing the risk of air leaks or sensor displacement. With two connectors, the sensor maintains a stable electrical connection, supporting consistent data transmission at the rated 12 volts.
