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.

    Got car serviced at local Jiffy Lube - where I was duped into a $75 engine flush. Next day the check engine light came on. Fortunately a mechanic friend was able to inspect the car before I spent a million dollars at the dealership and found that there were several loose and/or incorrectly attached hoses and connectors..

    I changed the air filter and this happened to me. A neighbor is a Toyota mechanic and told me about it when I called him about the check engine light.

    Happened during an oil change. Gas mileage was awful until I brought it back to the oil change shop.

    I had serviced the car (which I have been for years) check the air cleaner, then the engine light came on few days later. I brought to my Toyota dealership to see what triggered the light, they found this same hose came disconnected from the air cleaner housing. I asked how much for the repair- they smiled and said "all set" no charge.Good people.
