When changing the air filter, it is easy to knock off a hose on the air filter housing, which is part of the emission control system. If the vehicle is driven with this hose disconnected, the Check Engine Light will illuminate.

    Check engine light & VSC light come on together every time my air filter is changed. Hose comes off. Put hose on and disconnect battery to get the check engine lights to go off.
