1999 Honda Accord Trouble code 1399

Hi edabcd,

Wait to start lamp circuit.

Something new to me but I got a feeling something to do with the main relay.

Can the vehicle start when the code appears?

Any symptoms?

I would check it out at my office and get back to you.

Yes, car starts ok while code is present. However, can feel "a miss" in motor while running a highway speeds and gas milage very noticably affected. Have received suggestions to try the coil - make sense to you.
Thanks.

Hi edabcd,

It is possible for the coil to miss, but it should not be giving you any code.

Since it can start, dose the code show each time you start or intermittently.

Could not get any info for this code. Did you run any diagnostic data reading on the vehicle?

The code shows each time car is started. No, did not run any diagnostic data reading on the vehicle.
Thanks for your help.
Ed

Hi edabcd,

Someone with a Civic has the same problem as yours and it crossed my mind that the ECM might be possibly giving the problem. The Civic had one more code of misfiring.
