I have a 2003 Highlander. Whenever I get the oil changed, the check engine light comes on within a couple of days. I finally figured out that there is a hose under the air filter case that gets disconnected when the filter is checked. Just reattach the hose and the light will reset after a few restarts of the engine.

To reset a check engine light for a Highlander 2003, disconnect the battery for 10 minutes. After this time, reconnect the cables.
Check the engine coolant... Is it full? yes coolant level is full
If there is a cap on the radiator you can check to see if the radiator is full , and if it isn't , " top up " the engine coolant . Otherwise , you check the engine coolant level at the engine coolant reservoir when the engine is cold and maintain the level at the cold mark
Check coolant leaks with a visual inspection. Clean the engine, then see where the coolant reappears. Look under the water pump. Check engine oil to see if coolant is leaking into the oil.
