Volkswagen Bora circuit fault

How to solve the sensor fault of Volkswagen Bora? The sensor of Volkswagen Bora is faulty and can only be replaced, not repaired. Automobile sensor is the input device of automobile computer system, which converts various working condition information of automobile, such as vehicle speed, temperature of various media, engine working condition and so on. , converted into electrical signals, sent to the computer, so that the engine can be in the best working condition. The symptoms of vehicle sensor damage are as follows: 1. Symptoms of damaged speed sensor: the engine is unstable at idle speed; When the vehicle slows down to start or stop while driving. Instantaneous pause or flameout; Engine acceleration performance decreases; There is a deviation in the speed display on the instrument; Engine fault light is on; 2. The failure of the throttle position sensor indicates that if the throttle position sensor fails, the correct ignition advance angle and air-fuel ratio cannot be guaranteed. The throttle position sensor should be accurately adjusted to the specified voltage reading. If the adjustment is too low, the exhaust gas recirculation system will knock when accelerating because it does not provide enough exhaust gas in time. If the regulation is too high, the exhaust gas recirculation system will provide too much exhaust gas, thus reducing the power. 3. Description of coolant temperature sensor damage: If the coolant temperature sensor fails, the engine will have unstable idle speed, fire, flameout or increased fuel consumption. According to the manufacturer's regulations, the resistance value of the coolant sensor at different working temperatures should be tested with a multimeter.
