Or you could look in the FAQ for a much better write-up, including codes and what they mean, how to code check, and how to clear and reset the ecu.  DSC posted it.

Can't you just unhook the battery for like 24 hours to reset the ecu? &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/eh.gif" border="0" valign="absmiddle" alt=':eh:'>

I don't think so dr2if4ta0sx...

BTW, the writeup in the zilvia FAQ isn't 100% correct, I've been meaning to change it for months but don't remember the exact steps myself since it's been a couple months since I reset mine last.

Here is the steps I jusyt had to do it again.

You need to leave all the sensors connected
2nd of all, the check engine light WILL NOT turn off until you reset the computer, to do this:
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 and then start it again, this should of removed the code.
