Why isn't the valve timing offset data written?

When washing the throttle, someone else's computer read the data, which caused it.

After cleaning the accelerator, the car needs computer matching. Matching means that after the throttle is cleaned, the minimum closing angle of the throttle itself has been restored to the standard value, but the original correction value is memorized in the computer, and the memory must be deleted in the computer to restore the standard control data.

If the matching is not good, the throttle response is poor and the idle speed is high; After cleaning the throttle body, it is best to initialize it with a diagnostic computer. Many models can also manually match the throttle body. After matching, the idle speed is stable and the fuel consumption is the most economical. There is no difference between idle speed and before cleaning, indicating that the engine is working normally and there is no problem. Because the computer has a memory function, it has adapted to the throttle state before cleaning. Even a slight change in the opening of the cleaning throttle will be directly reflected on the computer. It is recommended to use a detection computer for matching.

The working principle of intelligent variable valve timing system is as follows:

When the engine changes from low speed to high speed, the computer automatically presses the engine oil to the small turbine in the driving gear of the intake camshaft, so that the small turbine rotates at a certain angle relative to the gear box under the pressure, and the camshaft rotates forward or backward within 60 degrees, thus changing the opening time of the intake valve and achieving the purpose of continuously adjusting the valve timing.
