Check engine light Code #520545 plus others HELP!

[Deleted member 677]

Once again I have a check engine light on, but this time I have an engine code on my dash. And I have several others on my PV3. Anyone know what the one on my dash or these others mean?

I did a search and none of those numbers appear in the service manual anywhere. Not sure what to tell you. What are its symptoms?

edit: I was able to find 520210/209. Those two are O2 sensors 1&2 and the /4 means “Driver Circuit Grounded”. The others don’t exist in the service manuals I have.

I'd check grounds and battery voltage. That many different codes might even point to loose battery cables...

I had the same results. The symptom was just a really stubborn cold start, as usual. The light came on 10 seconds after starting and trying to stall.

Thats a good thought. I will check that out.

So I found that my 02 sensor heater fault code was a blown fuse. But the others I still can't find. I also noticed that now my signals don't work. But I don't see a flasher relay or fuse for them. Any ideas why this would be?

 

[mark.lb]

Someone previously posted about a balky starter switch and they swapped the relay with the signal relay to sort the problem. They may know where the relay are hiding.

So I replaced the 7.5amp fuse listed as 02 heater and the signals worked after that. But immediately after turning the bike on, the fuse blew again.

Got a short somewhere. Did you do a fender eliminator? I’ve seen some posts lately about the tail harness not being tucked into the subframe well enough and the chain rubbing and wearing into it.

 

[ferraiolo1]

Yeah if you messed with your front or rear signals. Check your waiting harness.

there won’t be a flasher relay. Everything is controlled by the computer

No, I never messed with the signals at all. It all stopped working when the check engine light came on. They would work when I would replace the 02 sensor heater fuse. But the fuse would blow a few seconds after turning the bike on. I rode home from work with no issues. I was going out for a ride afterwards, but it wouldn't stay running during warm up. Thats when the check engine light came on, and everything else happened.
