What are the effects of Sonata sensor failure?

The impact of Sonata sensor failure is as follows: 1. Performance of the fault of the speed sensor: the speed sensing function is mainly to detect the speed of the electronically controlled vehicle, and the control computer uses this input signal to control the engine idle speed, lock the torque converter of the automatic transmission, shift gears of the automatic transmission, switch the engine cooling fan, cruise constant speed and other functions; 2. Symptoms of poor 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; Engine fault light is on; 3. Explain that the throttle position sensor is broken: If the throttle position sensor is unbalanced, 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. 4. 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.
