Wei Zhi fault light is always on, and the throttle position sensor is faulty. Help! ! !

Be sure to clean the throttle. Because the idle speed is unstable, the 4S shop always says that the throttle is too dirty and needs cleaning, and it will be fine after cleaning. It didn't take long for it to happen again. If so, it's not the throttle, and it's no use rewriting the system. The fault light should be something else. The brake light may not be on, resulting in a fault light. Idle speed has no solution. The radical solution is to replace the main control computer, which was replaced by the Wei Zhi organization at the beginning of this year. I was driving in Wei Zhi, and the situation you mentioned happened. I wish I had changed my computer. It's no use not changing the computer. Can't solve it. You can contact the 4S store and ask them to arrange a replacement. When I change it, it is free. If it's expensive at your own expense, I heard it will cost 4-5 thousand.
