What causes the Volkswagen EPC light to illuminate and report a camshaft fault?

Computer self-diagnosis system detects faults or abnormal phenomena. The following is an introduction about Volkswagen: 1. Introduction to Volkswagen: Volkswagen (German: Volkswagen) is an automobile manufacturing company headquartered in Wolfsburg, Germany, and is the core enterprise of the Volkswagen Group, one of the world's four major automobile manufacturers. 2. Volkswagen's brand culture: The history of the car's logo has undergone multiple changes, with the VW in the logo being the first letters of its full name. The logo appears to be composed of three "V"s made with the middle and index fingers, symbolizing the victory of Volkswagen and its products.
I've been driving a Volkswagen for several years. Last year, the EPC light came on and a camshaft fault warning popped up, which caused me quite a hassle. At first, I thought the engine was broken, but in reality, the most common issue is a malfunctioning camshaft position sensor—this component is responsible for monitoring the camshaft's rotation angle and sending signals to the vehicle's computer. In my case, the sensor had an internal short circuit, causing the computer to falsely report a fault, leading to sluggish throttle response and a noticeable lack of power while driving. Worn sensors, aging wiring with poor contact, or corroded connectors can also trigger this issue. Later, I used an OBD scanner to pinpoint the problem before getting it fixed. A reminder to other car owners: don't ignore this—when the light comes on and power drops, it also affects fuel efficiency. Get it checked at a professional shop promptly to avoid minor issues turning into major repairs. Regular maintenance, such as cleaning dust and inspecting wiring connectors, can prevent problems and save you both hassle and money.
