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.

    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.

    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.

    I really hate this issue!! It happens most oil changes, except at the dealer, and it's a big time waster to get it resolved. I need a picture of this so I can fix it myself. Advance Auto parts store is happy to run the diagnostic and reset the CE light for me.

    Same thing others describe. Filter change with 30 point checkup. Someone replaced the air filter with wrong version. Did not latch the cleaner housing down correctly, and hose was off the back. Weird, deep throaty/gutteral sound when accelerating. Now have to reset the LED and hope that's all that went wrong.

    After oil change, the check engine light came on. Hose was not connected.

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

    every time a tech looks at the air filter, the hose in back disconnects

    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..
