Why does my Honda Accord idle all the time?

The problem might have been caused by various sensors and valves in your engine, which you will want to inspect. The idle air control valve (IACV) controls the amount of air going through the throttle plate, which controls the engine’s idle.

Why is the idle air control valve not working?

When this happens, the job of the idle air control valve is to bring this deceleration down to a slow and smooth idle rather than suddenly cutting off the fuel supply causing the motor to die. When the idle air control valve is not working properly, this cause a disruption in this process resulting in the engine not being able to idle properly.

Why does my Honda Civic idle at 500 rpm?

Typically, a vacuum leak of some sort will result in a high idle above 500 rpm. The easy way to find out if there is a vacuum leak is to spray the hoses with starter fluid or brake cleaner. Make sure this is done on a cool engine. If any of the hoses are cracked or not sealed correctly, they’ll suck in the vapor and the car’s idle will change.

What does fast idle thermo valve do on Honda Accord?
