What are the symptoms of Buick Hideo sensor broken?

Damage to the sensor will have different effects. The following is the impact of Buick sensor damage. 1, the symptoms of speed sensor damage are: unstable engine idle speed; When the vehicle starts or slows down while driving, it stops or turns off instantly; Engine acceleration performance decreases; There is a deviation in the speed display of the instrument, and the engine fault indicator light is on. 2. The damage of the throttle position sensor will be manifested as: the throttle position sensor fails, and the correct ignition advance angle and air-fuel ratio of the mixture cannot be guaranteed. In order to ensure normal acceleration performance, the throttle position sensor must be correctly adjusted to the specified voltage value. If the adjustment is too low, knocking will occur during acceleration, because the exhaust gas recirculation system does not provide enough exhaust gas in time; If the regulation is too high, the exhaust gas recirculation system will react too fast, provide too much exhaust gas and reduce power. 3. If the coolant temperature sensor is broken, the engine will have unstable idle speed, fire, flameout or increased fuel consumption. In order to test the resistance of the coolant sensor at different working temperatures, a multimeter can be used to test according to the manufacturer's regulations. In addition, there is a body height sensor in the suspension, and the body height will change with the change of load. The height of headlights will also be automatically adjusted with the change of car body height.
