Can a citroen xsara picasso idle control valve make your engine rev to much?

Yes, a faulty idle control valve (ICV) in a Citroën Xsara Picasso can cause the engine to rev too much. The ICV is responsible for controlling the amount of air that bypasses the throttle valve when the engine is idling. If the ICV is faulty, it may allow too much air to bypass the throttle valve, which can cause the engine to rev too high. Additionally, a faulty ICV can cause the engine to idle erratically or stall. If you suspect that your Xsara Picasso's ICV is faulty, it is important to have it diagnosed and replaced by a qualified mechanic as soon as possible.
