A while back I lost my speedometer gear, Of course I got a check engine light due that it couldn't read my speed. I know that it also adjusts timing and fuel by reading the speed. I finally replaced my gear about a month later. All seems well, no more check engine light. My question is... do I need to un hook my battery to reset the computer for it to run right. I know if I don't the code will still be there.
