It's OBDI, you need to fix the cause.

Put black electrical tape over it.

You can "reset" it by disconnecting the battery, but like Ravine said, it's on for a reason.

It's probably your o2 sensor that's shot, have you tried scanning it to figure out what the problem is?

Just need a paperclip and the ability to count.
