Codes P1353 and P1356

[dodomrkc]

There is a service bulletin for the P1356 code (I am not sure of the SB# though, it is in the self help section here), I had it on my 2004 Road King.
I was able to get the dealer to download the software patch that cures this issue, and they did it for free under an "emissions warranty" that is good until the motor registers 16K miles.
Glider helped me with this back about 6K miles ago and the issue never came back. Good job.

Those codes could be caused by the PC or a number of other things also like plugs, plug gap, plug wires, loose plug tip where the wire joins on and even bad wiring on the injectors near the plug. If the bike isn't showing any missing, more than likely it was an intermittent malfunction of the ION sensing due to one of the mentioned problems above.

I would check out the above and clear the codes and see if they return again.

Welcome to the forum.

I saw where tightening the screws on top of your spark plugs would help. I did that and my code disappeared
