FI lamp, code 7, damn bike ...

Hi Guys and gals

Yesterday I was on a quick ride out after I cleaned my bike. Unfortunately after an hour of riding the FI lamp lid up. I turned off the ignition and waited 20 seconds, then turned the bike back on, FI lamp stayed off.
After about 15 minutes it turned back on and I rode home. I looked up the FI code, 1 long, 7 short seems to be the second throttle valve sensor. Now the big question, should I do something about it right away ? The motor is running fine.
I'll check later if there are any loose cables or connectors that got wet somehow, but what would you recommend doing ? FYI I tend to ride a lot, 1000 km a week is usual for me, my bike is the 2010 SD-R in case it matters.

Thanks for your help, appreciate it a lot.

Best regards
Jens

Search BGC or big grey connector, all your questions will be answered my friend!

Thanks, I will check it, but which one is the BGC, ok I guess it's THE big grey one but where do I find it ? I gave BGC a try on the search but I get like quadrillion search results.
I have the repair manual though, maybe you can point me where I can find it ?

Is it this one ?

Right side of trhe bike under the tank spoiler pannel in front of the coolant tank.
Clean dry and lube with dieelectric grease.

How do I get it out of there ? It's hooked to a piece of metal and I can't get in there to pull it off ?

Push down the connector plastic spring tab at the leading edge of the metal tab.............
