Is it necessary to clear the throttle when xrv reports fault codes indiscriminately?

If the throttle is not cleaned for a long time, carbon deposit and impurities will affect the accuracy of the throttle opening, and air containing impurities may enter the combustion chamber, which will affect the normal operation of the engine. Its most obvious performance is unstable idle speed. When driving normally, there will be a sudden feeling of oil collection, the power will be worse than before, the fuel consumption will also increase, and sometimes there will be problems such as starting difficulties and even engine failure.

Cleaning the throttle is best judged according to the power feedback of the vehicle. If the idle speed of the vehicle is unstable, it is difficult to start, and the power drops, it is not too late to clean the throttle. There are two ways to clean the throttle valve, namely, disassembly-free cleaning and disassembly-cleaning, each with its own advantages and disadvantages. The biggest feature of disassembly-free cleaning is its simplicity and convenience. Spray the throttle cleaner directly on the wiping cloth or directly on the throttle, and then scrub the throttle. The disadvantage is that the cleaning effect is average, which is suitable for the throttle that is not particularly dirty. Be careful not to spray into the pipeline behind the throttle, which will cause secondary damage to the throttle. Disassembly and cleaning is a little troublesome, and the whole throttle assembly needs to be removed, and then thoroughly cleaned with special cleaning agent before recovery. Although the steps are cumbersome, the advantage is that the cleaning effect is thorough and the maintenance price of 4S shop is relatively expensive. Different car brands need to reset the throttle opening after cleaning the throttle, otherwise the car computer has memorized the opening when there is carbon deposit. If it is not reset, the idle speed of the engine is unstable and the speed is high, and the result is not worth the loss. As long as the light goes out after ignition, it is normal. Don't worry, this is the self-test state after power on in your picture. These lights do not mean that the car is out of order. Only the lights that light up during driving or don't go out after ignition indicate that the car is out of order. You need to overhaul the meaning of these lights: the red P icon is the parking brake warning light, and the parking indicator light is the handbrake indicator light. When the electronic parking brake button is pressed or the hand brake is pulled, this indicator light will light up; When the brake is released, the indicator light will turn off EPC=ElectronicPowerControl (full name of electronic engine stability system); When a sensor fails or senses an abnormal situation, the fault light will light the battery indicator light: the battery light on the dashboard is a warning light for the generator not to generate electricity, indicating that it is consuming electricity. It goes out after the car is hit. It will light up when driving. Generally, in the case of poor combustion state, engine knocking and poor fuel quality, the engine fault indicator light will light up and should be repaired immediately.
