I got a check engine light on my bike so I went through the diagnostics and got the following:
P: no rSP
S: nonE Pn:68921-old
SP: nonE Pn:67439-05
t: no rSP

What does the "no rSP" mean and what does "Pn: 68921-old" mean? Thanks a lot guys. One more thing, if by the looks of it, I don't have any codes then why do I get the check engine light?

 

I am no expert but it seems that you do not have a current code Norsp= No response I take it you do not have a tach?
The "old" may be an old code, did you try clearing the codes and see if it comes back after you run the bike?
I also believe the "pn:#'s is for the related service manuals.
The check engine light might only come on intermitently because it may be a sporadic problem.

Don't take my word for it I am sure there are more qualified people here to set us straight!

Good luck

 

my 2c worth, not knowing what bike you have, but the p refers to the ECM, the S for the security/ turn signal module, the Sp for the Speedo and the T for the Tach.

Now I would assume you either ahve an ECM and the P showing no Response (No Rsp) says there may be an error here. I have had a simial prob when I don't go into diagnostic mode properly ( I am assuming you did this correctly).

Unless youhave a tach installed you will get a No rSP- this is normal. Just make sure everything is plugged in properly and there are no obvious broken wires in the cable route etc.

Cheers.
