How do you reset engine light 2003 Toyota Solara 2.4L and the odo on off solution did nothing?

Answer 1

With a few exceptions the only way to reset the "check engine" light is through an OBD II code reader. The light is on because there's an issue with the engine or some part of the emissions system (could be as simple as a loose gas cap).

To reset, borrow a code reader from an auto supply store that offers them (free). Plug it into the port under the dash to the right of the steering column. Follow the instructions on the reader (usually in the lid). You'll be given a number code by some readers, text showing the problem in others. Once you've identified the problem you can press the button that says something like 'turn off trouble light'. Be aware if you haven't repaired the problem the light is just going to come on again.

The exceptions include the afore mentioned loose gas cap lid and other emissions issues and some engine miss issues (faulty spark plugs or wiring) that, when repaired, will eventually allow the light to go out. It usually takes several on/off cycles of the ignition key before the computer figures out there issue is gone.

Bottom line, grab a code reader, identify the issue, fix it, turn off the light.
