Where is the Air Temperature Sensor Located?

The air temperature sensor, also known as the cabin temperature sensor, is generally installed below the dashboard and connected to the air conditioning ventilation duct via an air tube. Below is relevant information about the cabin temperature sensor: 1. The cabin temperature sensor consists of: the cabin temperature sensor and the cabin temperature sensor intake tube. The cabin temperature sensor uses thermistor material with a negative temperature coefficient characteristic. It is typically installed below the dashboard and connected to the air conditioning ventilation duct via an air tube. When air flows rapidly through, the resulting vacuum draws air to the in-cabin air sensor. 2. The cabin air temperature sensor transmits temperature signals to the ECU. The ECU analyzes and processes the signals, then sends commands to the blower motor to control its speed, thereby achieving the effect of regulating the cabin temperature.
With years of experience in auto repair, I can confirm that the air temperature sensor location varies significantly across different vehicle models. It's commonly found near the air intake of the AC system, either in the engine compartment close to the firewall or beneath the dashboard. During inspections, I always refer to the owner's manual first for confirmation, as incorrect positioning can affect AC heating/cooling performance - especially when weak cooling in summer serves as a telltale sign. These sensors are prone to dust accumulation and require regular cleaning to maintain accurate readings. Pro tip: Use compressed air to blow away surface debris. Proper sensor location aids in AC troubleshooting, saving both time and money on unnecessary shop visits while enhancing driving comfort.
When I first bought my new car, I specifically researched the location of the air temperature sensor. It's usually at the air conditioning unit's inlet, sometimes in the duct under the hood or behind the dashboard, varying by brand. I learned simple checks—misplacement leads to incorrect temperature readings, causing increased fuel consumption and inconsistent AC performance. During routine maintenance, gently wiping off surface dust can extend its lifespan. Understanding its location enhances driving safety and efficiency, like quicker AC response on highways to prevent fatigue. Always consult the manual or seek professional help for checks—avoid forcing parts open.
