I took out the battery fuse (80A)in a box next to the battery. Then put it back after 15 seconds. The clock had been reset but the check engine light is still on after driving about 5 minutes.

Near the battery is a fuse box...pull the 7.5A fuse (top row, 2nd from left) labeled "Back-up." Leave it out for at least 10 seconds. The ECU pulls "back-up" power off this circuit. Or, disconnect the negative battery terminal. You will need to reset the clock and radio. You should actually reset the ECU after ANY mod. Before I cleared the CEL, you might read it's code (if you havent done so) and correct the problem.
