Would a fuse cause the check engine light to come on in a dodge neon?

A fuse does not cause the check engine light to come on. Modern cars have a bunch of little sensors. Each one can set off the check engine light. You can hook your car up to a computer and check it out to find out which one it is. You can even hook up a wire and a little bulb and count the number of flashes. You can check it out. The number of flashes can tell you what is wrong. For example, on some chevrolets 015 is a sensor right above the thermostat. If that one goes off, it might be time to change the thermostat.
