Where is the fuse that controls the emission testing?

The fuse that controls the emission testing system is typically located in the engine compartment fuse box or the interior fuse panel of the vehicle. To find the exact location, refer to the vehicle's owner’s manual, which provides a diagram and descriptions of each fuse. If the fuse is blown, replacing it may resolve issues with the emissions system. Always ensure the vehicle is turned off before inspecting or replacing fuses.
