How does Ruifeng throttle match the old Ruifeng?

Ruifeng commercial vehicle needs matching after cleaning the throttle. First, you need to cut off the power, then disconnect the negative electrode of the battery, and wait for one minute before installation. At this time, the car will erase the memory of the on-board computer and restore the factory settings, and then start the car to complete the matching.

Throttle position sensor can also be called throttle opening sensor, which can judge whether the engine is in idle working state or compound working state through detection. The throttle position sensor is installed on the throttle with a constant variable resistor. When the idle contact is closed, it will output the idle working state signal to the computer. When the throttle is in other position, the idle contact is opened, and the computer can identify the engine load through the signal sent by the throttle position sensor, and then modify the fuel injection quantity of the engine. The throttle of a car is matched according to different models. The throttle of an ordinary car is one of the parts that need to be monitored every time it is maintained.

After changing the throttle, Ruifeng M4 can be matched manually. Turn on and turn off the key of the ignition switch for many times, and the on-board computer will delete the memory of the crude oil door, store the data of the new throttle, start the vehicle and run for a few minutes to complete the matching.
