產品描述 Description

Facet Engine Coolant Temperature Sensor Please Note: This Engine Coolant Temperature Sensor has many positions depending on the YMM, we advise you put your vehicle in the vehicle selector to verify fitment. WHT-002-287-B - O-Ring - For Part Type: Engine Coolant Temperature Sensor WHT-002-287-C - O-Ring - For Part Type: Engine Oil Temperature Sensor Engine Coolant Temperature Sensor The engine coolant temperature (ECT) sensor, or simply coolant temp sensor, plays a vital role in monitoring the engine's operating temperature and communicating this information to various vehicle systems. This sensor is located in the engine's coolant passage typically in the cylinder head or block. It works by varying its resistance based on the temperature: as the engine heats up, the resistance decreases, and as it cools down, the resistance increases. The ECT sensor sends this data to the ECU, which uses it for several critical functions, such as the air-fuel mixture, ignition timing, and control of the cooling fans and dashboard temperature gauge. There are many European applications where there is more than one coolant temp sensor, separating the signals used for engine ECU and other functions such as gauges and fans. A faulty sensor might send incorrect temperature readings to the ECU, resulting in poor engine performance. The most common example is if the sensor incorrectly signals that the engine is colder than it is, the ECU will enrich the air-fuel mixture unnecessarily, leading to rough idling, poor fuel economy, or even black smoke from the exhaust due to unburnt fuel. Conversely, if the sensor falsely indicates an engine overheating condition, the ECU might trigger warning lights, prematurely activate the cooling fans, or even cause the car to go into "limp mode," limiting engine power to prevent damage (however this is a rarer failure mode).

關於品牌 About the Brand

Facet Facet began in 1946 by Francesco Andriano with the core principles of dedication, skill, courage to do, and to innovate when he opened up his laboratory. Soon after WWII, Franceso Andiano founded F.A.C.E.T with his son Mario. They began creating tungsten contacts for the telephone industry which was then a potential market with rapid growth. Due to the materials used, they were able to enter into another market, now producing plated contacts for ignition components in the Automotive Industry. In 1961 the company expanded by now producing condensers followed by caps and rotors in 1966. Since the early 90's, FACET has transformed to accommodate the arrival of electronics which as been a large part to this day. Since then, FACET has put a strong emphasis on continuous process improvements which continue to this day.
