Default Eu7000is shutting down randomly. Code E-0A

I have a eu7000is generator powering a small catering trailer. The unit will randomly shut down and display a code " E-0A" code. I cannot find anything on this code. Does anyone happen to have a service manual that can decode this fault?

On more than one occasion the unit will start to have subtle rpm changes 100rpm or less then it will shut off as if the key was turned. Nothing changes on the display. The display stays illuminated as if everything was fine and I can scroll through the menus.

I took a video going through the menus and snap shot of when the code was set but do not know how to decipher what they mean. Any help is appreciated. Unit runs longer when we have a fan blowing on the inlet. Plenty of airflow and unit is serviced regularly. Has just about 1100 hours on it.

Thank you LeroyB. Can you think of anything that might throw this code. I assume there is an O2 Sensor monitoring the air fuel ratio. Any chance you could upload the checklist for troubleshooting the E-0A code?

I appreciate the help.

We are having the exact same issue. We took our generator in for service. It took them a while to diagnose it as a fuel pump. This worked for about 1 month, now same problem. Any advice would be great.

The following video is from January 2015. But, might it lead you to your issue?

Tried that it and was not the problem. For reference, the manual seen in the video shows a carburetor. The Honda EU7000is is fuel-injected. It has a throttle body with a single electric motor controlled butterfly valve. The fuel injector is a single injector that in inserted in the side of the throttle body. Thanks for your attempt to help.

I did however take the throttle body and injector apart. The butterfly moves freely and there is not build up or "fuel" gum AT ALL. At least on mine.

I have also already replaced the GCU. It ran fine for about a month or so and then back to the same old symptoms. I am so frustrated at this point. I feel like I have a boat anchor. I am so disappointed in this $4000 Honda. I have 3 Honda EU2000is, One EU3000is, and one EU6500is. NONE have given me a single problem. I maintain them to perfection (yes I even have hour meters on the EU2000is). Never leave fuel in them and start/use them monthly. This is my first bad experience.

I simply can't figure this generator out!

I'm sorry my post was of little help. I know how frustrating it can be, when you know the problem is right in front of you, but you just can't see it.

Maybe send a PM to the "Honda" guy on this site?

Just an update for the next guy who runs into this problem. I ordered a new fuel pump and filter after I ran through the algorithm in the repair manual. The generator is up and running like a champ.

If you have a similar problem, I'd start with the filter and then the pump. I just got both and my problem was solved.

I had the same problem, I installed a NEW Pump with filter sock and a new spark plug,.THE only thing I cant find is a procedure to reset the error codes on the Imonitor on The Honda Generator EU7000IS.
IF you know Please help.. Id like to know if I am running normal again other than the sound and performance

Thanks
Rich

I have just converted our 7000is to propane and saw this error code until we got the fuel/air mixture correct by changing the fuel injector orifice. It appears to be triggered by the oxygen sensor.
Makes sense to me that it would happen if your air or fuel filter is dirty. Certainly try cleaning both before doing something more drastic like changing the fuel pump.
