I need a shortcut to find out why I keep blowing my engine control fuse. I have replace the engine coil pack. I think that there is a short somewhere. Pulled a code 43 from the OBD.

There are no shortcuts to find electrical shorts. Try unplugging the o2 sensors farthest away from the engine.One at a time, if there is a shorted heater circuit, it is possible that the o2 is blowing the fuse.

Suggested Repair

Unplug the oxygen sensors farthest from the engine one at a time to see whether a shorted heater circuit is blowing the engine control fuse.

The expert says there is no shortcut for finding electrical shorts and recommends unplugging the farthest O2 sensors one at a time to check for a shorted heater circuit.
