I have all these codes now. It happened 50 miles after I refilled my car with unleaded regular after seeing for two tanks how my car reacted to non ethanol premium. so no code with the premium, codes 50 miles after the unleaded regular. Any relation?

And should I just change out the ELD? I hear I have to get the entire fuse box. Is that right? Or how do I replace it? Its kinda hard to find info on this since the issue is mostly on civics.

 

o2 sensor?

 

Also possible fuel filter or fuel pump. Test the fuel pressure.

 

o2 sensors are a year old but could be faulty. fuel pump perhaps but thats apparently not common in hondas. Im focusing more on the ELD dictating all this as a possibility. Its hard to find info on it with accords.

 

Per the FSM, reset codes, start car and turn on headlights. Does code p1297 appear? If so, replace ELD. http://www.elementownersclub.com/for...ad.php?t=51803

 

Apparently the ELD on my car cannot be replaced by itself and I need to buy a new fuse box if its the issue. But the code does not come back on after I do this.

 

If the code reappears you probably have a flaky ELD. See . Although it's for a Civic I'd bet the Accord ELD is serviceable.

 

It is not actually. The 5th gen accords have the ELD built into the fuse box. But it seems based on the code troubleshooting that the issue may be a connection more than the ELD because the CEL comes on randomly. Im going to check the g101 ground and see if its being grounded correctly. The other two codes may be o2 sensor issues though. I'm not sure yet.

 

Update on this post. This was a while ago...
But the 1297 went away after wiggling the ELD wires and the other two went away with a new OEM o2 sensor. Dont buy aftermarket sensors.
