2002 Toyota Highlander ProblemsCheck Engine Light Due to Failed Oxygen Sensor Component
The Check Engine Light may illuminate because a component of the oxygen sensor stops working. As a result the engine computer is unable to determine the proper ratio of air to fuel for the engine. Replacing the failed oxygen sensor should correct this concern.
A problematic center airbag sensor can cause the airbag malfunction light to illuminate.
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.
