Check engine light?

[penk]

I hate these idiot lights. My yellow engine light just came on. Oil pressure is good. Its running beautifully. No obvious electrical issues. Wtf?

Mine randomly comes on every so often with no obvious issues. Usually goes away. Doesn't stay on long enough to get a scanner on it.

What code is it throwing?

I just found out you can check codes without an ODB reader. I'll check in the morning I'm already in bed.

Wonder if I'm doing this wrong. Hold button down and turn on. I dee "2.5". Flick off and on three tines, dash self test completes. Is the 2.5 the answer? That's an idle sensor right?
