Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Sensor String: Notes
Sensor string consists of an in-car sensor, an ambient sensor, and temperature control lever. The three units are connected in series in order to send a control signal to amplifier. As ambient or in-car temperatures vary, resistance of this series circuit is varied by sensors and also by temperature control lever/thus creating a variable signal received by amplifier. In-car sensor is located behind a grille in instrument panel. Ambient sensor is located in plenum panel behind glove box.
