Where is the outdoor temperature sensor of the Sagitar located?

After removing the left fog lamp grille, you can see the wiring harness extending to the left side of the condenser. 1. Introduction: A temperature sensor (temperature transducer) is a type of sensor that converts temperature variables into standardized output signals for transmission. Temperature sensors can be divided into two major categories based on measurement methods: contact and non-contact types. According to the characteristics of sensor materials and electronic components, they are classified into thermistors and thermocouples. They are widely used in temperature detection, monitoring, display, temperature control, overheating protection, and other fields. 2. Principle: It utilizes the principle of resistance change of a thermistor at different temperatures. As the temperature rises or falls, the resistance of the thermistor increases or decreases, and the ECU captures the voltage change to obtain the outdoor temperature data.

The other day when I took my Sagitar for maintenance, I specifically asked the technician about this. The ambient temperature sensor is usually hidden behind the front bumper, to be more precise, in the area between the grille and radiator. It's quite a clever design - it avoids mud splashed up by the tires while ensuring unobstructed airflow. On my 2019 model, it's located inside the driver-side fog light housing, with the probe facing outward mounted on a bracket. Replacement isn't complicated either, just two clips. When washing the car, be careful not to spray high-pressure water directly at that spot, though rain isn't a problem. If the dashboard temperature display starts jumping around or shows dashes, you should check if flying stones have damaged the probe wiring.

As a long-time owner of a Sagitar for 5 years, I can tell you the location of that little gadget. It's basically fixed on the inner side of the front bumper near the grille, usually located above the license plate mounting position to the left or right area, and near the fog lights in some model years. This little thing is directly exposed to the intake airflow, so it measures temperature very accurately. The last time I cleaned the engine compartment, I saw it—a black plastic piece about the size of a fingernail connected to wires. If the grille is covered by a plastic bag after parking, the reading might be inaccurate. To check if it's broken, drive about ten kilometers and see if the temperature changes normally on the dashboard. If the display doesn't change at all or shows a significant difference of several degrees, it's basically a sensor malfunction.

I had this part replaced at the auto repair shop before, and the mechanic showed me its location after removing the front bumper of my Sagitar. The ambient temperature sensor is embedded right at the front of the front bumper reinforcement, to be precise, it's mounted in a plastic bracket on the radiator support, right next to the crash beam. This design is quite reasonable—while driving, the oncoming air can directly reach the sensor probe, yet it doesn't easily get submerged during rainy conditions. If the temperature display on the dashboard consistently reads higher than the actual temperature in winter, it's most likely due to the residual heat from the engine affecting the sensor after parking. From my experience now, checking the temperature value about fifteen minutes after driving provides a more accurate reading. Although this small component is tucked away in a hidden spot, it's actually quite reliable.

I've studied the sensor layout of the Sagitar, and the specific location of the outdoor temperature probe varies slightly depending on the model year. In earlier models, it was mostly placed inside the inner fender on the driver's side, while newer models generally integrate it into the slot of the central grille's crash foam. The installation angle is designed at 45 degrees facing forward, which ensures accurate environmental temperature detection while preventing rainwater backflow. Once during a winter road trip, I noticed the temperature display malfunctioned, and it turned out the sensor wiring harness had been corroded and broken due to contact with melting snow agents. I'd like to remind everyone to promptly clean any accumulated water inside the front bumper after car washes, especially for owners who have modified fog lights, to check if the probe is obstructed. A simple test method is to compare the real-time temperature difference between the car's thermometer and a mobile weather app.

After replacing the front bumper in the last rear-end collision, I finally got a clear look at this small component on the Sagitar. The outside temperature sensor is directly clipped into a plastic bracket above the front bumper's crash beam, positioned right between the main radiator and the condenser. The mechanic mentioned it's intentionally installed on the windward side without touching any metal parts, allowing airflow to sweep over the probe during driving without interference from engine heat. For regular car owners doing their own inspection, standing at the front of the car and looking into the grille, the black square-headed part with a wiring harness is what you're looking for. When replacing it, make sure the connector's waterproof cover is securely fastened. A few years ago during heavy rain, I encountered abnormal temperature readings due to oxidized wiring, which was completely resolved after applying some conductive paste.
