產品描述 Description

NOTE: 20mm 2 Pin This replaces the original black switch used on some models. Includes O-ring p/n N90316801 . 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

VNE VNE GmbH was founded in 2001 by Volker Natorp in Hamburg, Germany. Volker has a long, storied history in the automotive field. He began his career in the 1970s working for Wulf Gaertner and in the 1990s eventually branched out on his own to start his own sales repping agency. During that time, he represented TMD Friction (Pagid/Textar) and managed all of the North American sales for them and eventually added Schaeffler Automotive to his roster. In 2007, VNE GmbH relocated to Ganderkesee, Germany and was renamed VNE Automotive GmbH & Co. With continuous growth, the decision was made to solely focus on developing VNE Automotive and, in 2014, the focus became reality with the commissioning of a new warehouse and office space. Today, VNE Automotive prides itself on never having followed the aftermarket trend. VNE Automotive operates in a highly specialized, niche product sector, by only offering OEM automotive spare parts to more than 50 countries worldwide. This is evident from the unique, and sometimes hard to find, product groups spanning engine management, body electrical, and brake systems.
