What will happen if Nissan Sylphy sensor is broken?

Nissan Sylphy sensor failure has the symptoms of vehicle speed sensor failure: 1. The engine is unstable at idle speed; When the vehicle slows down and stops while starting or driving, there is an instantaneous pause or flameout phenomenon; Engine acceleration performance decreases; There is a deviation in the speed display on the instrument; The engine fault light is on. What will happen if the sensor of Nissan Sylphy is broken? 1. Symptoms of broken speed sensor: the engine is unstable at idle speed; When the vehicle slows down and stops while starting or driving, there is an instantaneous pause or flameout phenomenon; Engine acceleration performance decreases; There is a deviation in the speed display on the instrument; The engine fault light is on. 2. It shows that the throttle position sensor is broken: if the throttle position sensor is out of balance, the correct ignition advance angle and air-fuel ratio of the mixture 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 not provide enough exhaust gas in time, and knocking will occur when accelerating. If the adjustment is too high, the exhaust gas recirculation system will react too fast and provide too much exhaust gas, thus reducing the power. 3. Damage of coolant temperature sensor: 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 should be tested with a multimeter at different working temperatures. Nissan Sylphy sensor failure has the symptoms of vehicle speed sensor failure: 1. The engine is unstable at idle speed; When the vehicle slows down and stops while starting or driving, there is an instantaneous pause or flameout phenomenon; The acceleration performance of the engine is reduced; There is a deviation in the speed display on the instrument; Engine fault light is on, etc.
