What is the fault code of the engine fault?

This display means that the engine system is faulty. Generally, there is too much carbon deposit in the throttle and fuel injector to pass the self-inspection fault alarm. Cleaning the throttle valve and fuel nozzle can eliminate the fault.

In the case of excessive carbon deposition, the friction between the throttle and the inner cavity wall increases, which leads to the failure of the throttle to close normally after opening. When the car starts self-checking, the fault light will light up. Throttle is a controllable valve for air to enter the engine, which is connected with the air filter above and the engine cylinder below. Figuratively speaking, it is the throat of an automobile engine. It is related to the acceleration of the car, keeping the throttle clean, keeping the car accelerating smoothly and reducing fuel consumption. Specific cleaning methods:

1. Remove the engine hood to facilitate the removal of pressure pipes and other pipelines under the hood.

Caution: Do not drop the screw into the engine; When disassembling the pipeline outside the pressure pipe, you can warm the car first.

2. Remove the throttle:

Remove the screw and ferrule for fixing the throttle valve, take out the throttle valve and put it on the rag.

Precautions: cover the snorkel to prevent foreign objects from entering the body.

3. Clean the throttle:

Most of the things attached to the accelerator are a mixture of oil and gasoline. Spray the cleaner on the dirty place and wipe it later.

Precautions: It is easy to hide evil in the gap, so it should be wiped clean.
