Regal sensor is broken. What are the symptoms?

The symptoms of a broken Regal sensor are as follows: 1, and the symptoms of a broken speed sensor: the engine is unstable when idling; When the vehicle starts or slows down while driving, it stops or turns off in an instant; Engine acceleration performance decreases; There is a deviation in the speed display on the instrument; Engine fault light is on; 2. Bad performance of the throttle position sensor: 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, the exhaust gas recirculation system will not provide enough exhaust gas in time, and it will knock 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. Signs of damage to the 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. There is a body height sensor at the suspension, and the height of the body will be different due to different load conditions. According to the change of body height, the height of headlights will be adjusted automatically.
