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.

Go call the Toyota car company or headquarters and ask the people who made the car.

For a 2004 Toyota Highlander, the recommended engine oil is 5W-30, which provides optimal performance and protection in various temperatures. It's best to use synthetic or synthetic blend oil for improved engine efficiency and longevity. Always check the owner's manual for any specific recommendations or requirements based on your driving conditions.
Check the coolant reservoir in the engine compartment. There are marks to assist you with proper level. If it's empty you need to add coolant ASAP.

In a 2002 Toyota Highlander, the check engine light is not controlled by a specific fuse; instead, it's part of the vehicle's onboard diagnostics system. However, if you're looking for the fuse box, it is typically located under the dashboard on the driver's side and under the hood in the engine compartment. You can check the fuses related to the engine management system, which may impact the check engine light, but there's no dedicated "check engine fuse." Always refer to the owner's manual for specific fuse locations and functions.
