Are you able to reset the code? Can you make the "check engine" light go out?

Here's the procedure from the IPD catalog. (You have to view all the codes at least once before resetting.)

Ignition on, test lead in socket A2.
Press the button for at least 5 seconds and wait for at least 3 seconds.
The LED will blink rapidly. (Actually, mine just comes on steady at this point)
While it's blinking (or in my case, ON) Press the button for at least 5 seconds and release.
The LED will go out.
Turn off the ignition.
Turn on the ignition and check codes. Should just be the 1-1-1. (No Codes)
If there are any, read and clear them, then attempt the reset again.
Turn ignition off, remove jumper from A2 and start car. Should be no CE light.

If you are sucessfull in resetting and your CE comes back on shortly thereafter with an 02 code, check for vacumn leaks at the elbows mentioned on Bay 13.

Good luck
