How to match the electronic throttle after cleaning?

There are two matching methods after throttle cleaning: the method of learning idle speed value with diagnostic instrument and the method of manual learning. After cleaning the throttle, it is recommended to use a diagnostic instrument for matching. This can ensure that the basic idle speed value of the engine is well corrected during ignition, and ensure the stable idle speed value and good fuel consumption when the vehicle is driving. Manual operation takes some time and experience, so it is recommended to go to a repair shop and use diagnostic equipment to match the idle speed value. There are three common methods of throttle matching: manual matching, power-off matching and diagnostic instrument matching. Specific methods are: 1, manual matching method. The throttle matching of machine code adopts manual reset mode, and the telephone switch is turned on/off for many times, and the on-board computer will erase the original throttle memory and save new throttle data. Just to verify whether the vehicle can run normally; 2. Power-off matching method: After changing the throttle, disconnect the negative pole of the battery for a few minutes, and the vehicle will enter a dormant state, during which the original memory of the on-board computer will be restored to the factory settings. However, this method is only suitable for resisting vehicles, as long as it is tested by normal vehicles; 3. Diagnostic instrument matching method: read the data with a special diagnostic instrument, and then follow the steps to zero the adaptive value, clear the fault code, start the vehicle and work normally, indicating that the matching is successful.
