This VIAS control valve is typically the part that needs to be replaced for the P1800 code. However, we cannot guarantee this will fix your issue. Other things could be failing on your vehicle. (Especially if you have other codes besides the P1800). After this is installed, the code still needs to be cleared from your vehicle. A scan tool is required for that.
