Matching method of low idle speed after Corolla power failure

As follows: 1, turn the key to the power gear first, and never start the car, that is, the engine is turned off.

2. After standing for about 15 seconds, quickly step on the accelerator pedal to the end, be sure to step on it quickly, hold on for 15 seconds, and then quickly lift the pedal.

3. Then close the key door, take out the key and let it stand for about 15 seconds.

4. Start the car normally and complete the matching.

After power failure, the throttle learning value will automatically return to zero! Because the throttle will be dirty in daily use, the throttle motor will constantly adjust the idle angle to stabilize the idle speed. This is the learning value of the throttle!

So there will be idle instability after power failure! If the throttle is not very dirty, then after driving for a certain distance, it will be normal to idle after learning the throttle again! On the other hand, if the throttle is dirty, it is recommended to clean the throttle, then unplug the throttle insurance and cut off the power again! Reinstall the safety and connect the battery after 1 minute, which will definitely solve the problem!
