What happens when the Volkswagen sagitar sensor is broken?

The fault symptoms of Volkswagen sagitar sensor are as follows: 1, and the fault symptoms of vehicle speed sensor: the engine is unstable at idle speed; Instantaneous parking or flameout occurs when the vehicle starts or slows down while driving; Engine acceleration performance decreases; There is a deviation in the speed display on the instrument; Engine fault light is on; 2. Indication that the throttle position sensor is damaged: If the throttle position sensor is out of tune, 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, knocking will occur when the exhaust gas recirculation system cannot provide enough exhaust gas acceleration in time. If it is set too high, the power will be reduced because the exhaust gas recirculation system reacts too fast and provides too much exhaust gas. 3. Signs of 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, a multimeter should be used to detect the resistance value of the coolant sensor at different working temperatures.
