2003 Toyota Highlander Problems

Check 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.

Airbag Light Due to Problematic Center Airbag Sensor

A problematic center airbag sensor can cause the airbag malfunction light to illuminate.

Check Engine Light Due to Failed Oxygen Sensor

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.
