Tianjin Free Ship Throttle Cleaning

The plug you mentioned is a speed sensor, not on the accelerator, but beside it.

Through your written introduction, I personally put forward the following suggestions, hoping to help you.

First of all, many people have a misunderstanding. A car that is not an electronic throttle will not be equipped with a computer after cleaning the throttle. What needs to be done is to read the idle speed and intake data flow of ECU with a computer.

Your problem now is that the neutral idle speed is about 1300 rpm, and it will return to the normal value (about 750 rpm) only when the car comes to a complete stop. Why? However, when the speed sensor is pulled out, the fault disappears.

This is really a strange thing. It stands to reason that the two are not related.

Through your words, the possibility of idle motor failure can be completely ruled out. It can't return to the normal value when it is in neutral because the speed of the car has not dropped, not because of itself. Also, you don't have to worry that the maintenance staff will change your throttle. The workshop staff can't change it at all, and there is no need to change it.

It is recommended to focus on the following:

1, speed sensor: focus on checking the working conditions and lines of the speed sensor;

2. On-board computer (ECU): It is possible that the parameters in it are set incorrectly when leaving the factory, or there are invisible faults that cannot be removed, resulting in faults;

3. Throttle: Whether the throttle line or throttle sensor is stuck or the line is faulty.

I hope the above answers can help you.
