Shanghai Volkswagen Polo can't afford gas. What should I do after replacing the throttle position sensor?

The car doesn't mean changing things casually ~ especially things like sensors ~ it doesn't matter how many sensors you change before you find the exact problem ~ ~ The pineapple car takes an electronically controlled throttle. All the signals are input and output from the computer board ~ ~ Determine when this problem occurred in your car ~ How long did it take ~ ~ How did you find that you couldn't afford to refuel ~ ~ The solution is to turn on the key first to see if the throttle is on ~ You have to take down the pipe in the air cabin to see it ~ If the throttle is on, it's very simple ~ Step by step, the air cabin has an air flow sensor ~ Check if there is any problem, and if there is no problem, just look at the air cabin. No problem ~ let's see if the engine exhaust is heavy. If it is not heavy, then use the decoder to adjust the fault code ~ if the fault is not displayed ~ then there is no way ~
