When you see the "Check Engine" light on your Toyota Camry's display panel, it has illuminated because of the ECU, or "Electronic Control Unit." This is a computer that stores codes sent to it by sensors positioned throughout the vehicle. When this light comes on, you should take your vehicle to a qualified mechanic or fix it yourself as soon as possible. Once the problem is fixed, you can reset the system and turn the light off manually.
Locate the fuse panel cover under the steering column. Pull down on it with your fingers to remove it.
Examine the diagram on the fuse panel cover and find the electronic control unit fuse.
Remove the fuse puller from inside the fuse panel and use it to pull the fuse out for the electronic control unit.
Put the key into the ignition and turn on the car but don't turn over the engine. Wait a few minutes then put the fuse back in place. You should notice the check engine light blinking a few times on the instrument panel, then it will go off.
Turn off the engine and replace the fuse panel cover.
