The idle control valve ensures that your car remains at the same speed when you are stationary. While driving, the throttle body, controlled by the accelerator pedal, ensures the supply of air to the engine. When your car is stationary with the engine running, the throttle body is closed. At that moment, the idle control valve takes over the air supply. The valve keeps the engine speed low so that fuel consumption is minimal. A defective idle control valve causes an irregular speed and high fuel consumption. The engine can also stall spontaneously when changing gears.
Idle control valve broken
A broken control valve can no longer properly regulate the air supply during idling. This causes an irregular speed when stationary and higher fuel consumption. To safe fuel and money, you want to replace a defective regulator as soon as possible.
Symptoms of a faulty idle control valve include:
- A fluctuating speed while idling. A normal speed is the minimum speed, which is about 700 rpm.
- Spontaneous engine stalling when changing gears.
- High fuel consumption.
- The engine indicator light is on.
Do you recognize one of the symptoms? Then check the idle regulator and replace this part, if necessary.
