What is the reason for the throttle jump of Wuling Light?

Cause analysis: first, the one you repaired the car did not clear your ECU fault code; The original fault code is still in the ECU, and when the car works again, the ECU cannot correctly judge the working state of the sensor. The ECU will classify this as a fault problem and give an alarm. 3. The reasons for the damage of the throttle sensor are: the voltage is too high, the intake pressure of the throttle valve is higher than the working value and uncertain factors. 4. Poor line contact. Check the interface of each line. 5. If you troubleshoot the ECU yourself, you can temporarily loosen the negative grounding wire of the battery and let the ECU discharge naturally, but this will have the defect that the original data of the ECU is lost. It is best to use a car fault code reader to eliminate it.
