How does the new Santana clean the throttle and need a computer reset?

It is best to do computer matching when cleaning the throttle. At this time, the computer is based on some relevant data of the throttle before cleaning. If it does not match, it may cause problems such as increased fuel consumption.

Because the computer has storage function, it has adapted to the state before throttle cleaning. After cleaning, the throttle opening is directly changed (even a little) to the computer. There are two kinds of signals. The common phenomenon is that the idle speed changes from high to low or from high to low, so it is suggested to use the detection computer to match.

After cleaning, the air inlet changes little. However, the change of the throttle after cleaning is invisible to the naked eye, so initialization is needed.

Extended data:

The composition of electric throttle can be roughly divided into the following parts: throttle, electromagnetic driver, potentiometer, controller (some of which are not directly controlled by ECU) and bypass valve. Its fault characteristics are divided into two categories: hard fault and soft fault. Hard fault refers to mechanical damage, soft fault refers to dust, inadaptability, etc.

Hard fault: The resistance part of potentiometer is made by spraying a layer of carbon film on polyester substrate, which is actually a very low-level preparation process with low wear resistance. To put it bluntly, it is not as good as the potentiometer of our usual household appliances.

Soft fault: people are usually troubled by cleaning the throttle because in most cases, the throttle opening is too low. Air flows through the gap of the throttle valve at high speed (tens to hundreds of meters per second). The influence of dust deposition on airflow exceeds the adjustment ability of throttle.
