Check engine with cover on

I have a very weird issue goin on. My 2007 etec 250hp keeps kicking the check engine light and alarm when the cover is on. When the cover is taken off the engine lights goes off. When plugged into the diagnostic it does not bring up any code. If you go to put the cover on the light and alarm trip again. This has happened repeatedly and i cannot seem to chase it down. Was hoping someone has had a similar issue. Not sure if maybe an airflow or bad sensor. Engine runs great with no other codes coming up.

Re: Check engine with cover on

If nothing shows up in a visual inspection of the powerhead, wiring , and cover, you may need a tech to ride along with a laptop to monitor the engine data as the problem develops.

The factory recommends that a properly trained technician service your Johnson or Evinrude outboard motor. Should you elect to perform repairs yourself, use caution, common sense, and observe safety procedures in the vicinity of flammable liquids, around moving parts, near high-temperature components, and working with electrical or ignition systems.

The information offered here is only general in nature and should not be construed as complete factory approved procedures, techniques, or specifications. Always use the proper service manual for your motor, up-to-date service literature, the correct tools, and have an understanding of how to proceed with troubleshooting and repair methods. If you are unsure or uncomfortable with a procedure, a situation, or a technique, enlist the services of a factory trained technician.
