Had a engine check light pop up after my last 5K maintenance. Dealer checked it out, it was a "P" ECM code, said it was a minor "nuisance" code, I can't remember the number (dammit).... Anyway it went off, stayed off, and off I went, no problems.

Now a couple of weeks later, the check light popped back up, I checked the codes, but on the "P" ECM menu, where I expected to see "none" or a code, I got "no rSP". What the heck is that? "no response"?

Was the stop/run switch in the run position?

Yeah, but I'm going to try it again just to make sure.

I did receive "none" on the "S" and "SP" mode. Didn't try the "T" mode since I don't have a tach.

Thanks Zeus, I really appreciate the help.
