2002 Toyota Highlander ProblemsCheck Engine Light Due to Hose Off of Air Filter Housing
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.
A problematic center airbag sensor can cause the airbag malfunction light to illuminate.
On higher mileage vehicles, an engine misfire may develop and/or the Check Engine Light may illuminate due to a failed ignition coil. It is not uncommon to replace all the coils when the first one fails in order to prevent return trips to the repair shop.
