Found this helpful so:

how to reset the ECU:

"Find the computer(Behind the plastic piece by the passenger foot
Pull it out
Turn your key to the on position
You will see a flathead screw looking bolt on 1 side of the computer. Turn this fully clockwise
Wait at least 2 seconds
Turn it back to fully counterclockwise
This will then show the trouble code - (The check engine light will blink to show this, for instance, blink..blink..blink......blink..blink, will be 32)
After you read the code, you can start the engine
Turn the bolt back to the clockwise position for at least 2 seconds(While running)
Turn it back to the counterclockwise position
Now shut the car off and then start it again, this should of removed the code."
