07 Honda crv2.4 shows no learning at idle speed.

Failure to learn idle speed is usually caused by poor throttle seal or throttle failure. You can re-check the air tightness of the throttle or replace the throttle and send it to the repair shop for solution.

The idle speed of a car refers to a working condition. When the engine is idling, it is called idling, that is, the gear of the car is neutral. The engine speed at idle speed is called idle speed. Idle speed can be adjusted by adjusting the size of air door. Idle speed means that the engine is "not working". When the engine is running, if the accelerator pedal is completely released, the engine will be at idle speed. When adjusting the idle speed, the speed should not suddenly increase or decrease, otherwise it will cause early wear and tear to the engine, so it is best to adjust it in the automobile maintenance department.
