A few weeks ago I started getting the check engine light coming on and off. I check the spark plug connections... was fine... Didn't get a code stored in the console diagnostics. The motor is running great, better than ever been since I did a oil change to full synthetic after I saw the light the first time. The thing I notice is if I wash the bike or it's early in the morning and there's some moisture it tends to come on and off more. Has anyone delt with anything like this... I think it has to be some sensor or wire connection as the motor is running perfect.

do you have a PCIII installed. Ran into this on Sunday when I washed the bike. Check the PCIII connectors, one of my retained about 2 oz of water and is now sealed water tight. Until I pulled the connector apart and dried it out the bike ran weird with all sorts of lights/codes.

 

What is a PCIII?
