Left fog light position. Below is an introduction about temperature sensors: 1. Introduction: A temperature sensor (temperature-transducer) refers to a sensor that can sense temperature and convert it into an available output signal. Temperature sensors are the core components of temperature measuring instruments and come in various types. They can be divided into two major categories based on measurement methods: contact and non-contact types, and can also be classified into thermal resistors and thermocouples based on sensor materials and electronic component characteristics. 2. Selection considerations: Whether the temperature of the measured object needs to be recorded, alarmed, and automatically controlled; whether remote measurement and transmission are required; the size of the temperature measurement range and accuracy requirements; whether the size of the temperature measurement element is appropriate; in situations where the temperature of the measured object changes over time, whether the hysteresis of the temperature measurement element can meet the temperature measurement requirements; whether the environmental conditions of the measured object will damage the temperature measurement element; the price and ease of use.
The ambient air temperature sensor on the Buick Excelle is typically located near the front grille area or beneath the front bumper. Specifically, when you crouch down to view the front of the car, it's easily found near the air intake on the driver's side. When I first drove the Excelle, I encountered inaccurate temperature readings and discovered a small plastic probe on the radiator grille cover. Its low placement is designed for direct contact with outside air, providing accurate data to the vehicle's climate control system. However, it's prone to clogging from road splash or dust, causing dashboard readings to fluctuate and affecting automatic temperature regulation. During self-inspection, gently wipe the probe with a damp cloth. If the issue persists, replacement may be necessary - the part is inexpensive, costing around a hundred RMB. Remember to avoid high-pressure water jets in that area to prevent damage. Proper maintenance of this sensor can significantly enhance driving comfort.
In car repair experience, the ambient temperature sensor of the Buick Excelle is mostly fixed on the inner side of the front bumper liner or on the right side of the fan shroud. It is installed at a low position to accurately read the external temperature and help optimize the operation of the air conditioning system. If you notice unstable temperature readings inside the car, you can lift the vehicle and check for a probe connected to a wiring harness behind the front wheel, located near the cooling module interface. This sensor is fragile and prone to dust accumulation, which can cause inaccuracies. It is recommended to clean it during routine inspections. The replacement process is not overly complicated; a technician will use a wrench to remove small components of the front bumper but ensure the connector is secure. Be cautious when driving on rough roads to avoid damage from stones. The repair cost is moderate, with labor typically taking less than half an hour, mainly to prevent issues that affect overall comfort.
