07 summit 800 check engine flashing. Not airtemp or knock sensor.....

Runs great, but engine light is always flashing. Only get the normal beeps at startup.
Not the dess, it runs great.
Tried another airtemp and knock sensor already.
Checked all the wires and connections on carbs and rave solenoids. Checked all impulse and vacuum lines.

Any way to test the T.P.S?
Any other sensors i missed?

Any ideas from you people that know things?

BUDS

These are always tuff to guess. I would head to the dealer and see what the fault code is.....at least then you have a place to start. The 07's were finicky being the 1st year 800r/ECM.

Light

Check all your wiring pluggins. Mine does that when the air box sensor is unplugged.

Brought it into the dealer and it was storing a detonation code. They said that once detected, the check engine light will flash until the code is cleared.

I'll buy that as I had that exact same issue last year. I had experienced a little deto due to crap fuel and BAM came the light and could not get it to go out until BUDS cleared it.
