I keep doing the fix-a-ford thing (disconnecting the positive cable) to reset the thing but it always finds its way back. The light shuts off for about two to three months then comes back on. Thanks for your help.




Contact your dealer to see if you qualify for a computer reflash under your emissions warranty. If you are out of 8/80 federal emissions (or in California - 7/70), the charge is modest.

For a LOT of detailed background info, click on SEARCH and enter "P0420" as your search keyword.
