F1 code 7 flashes

Hey guys was riding home tonight and looked down to see error code light on. Bike was going perfectly and the light was just on. Pulled over and it seemed to do 1 long flash followed by 7 quicker flashes. The only thing i could see in the Workshop Man was this



Sensor for 2nd valve throttle. Anyone know exactly what this is and is it something I could have nudged/damaged when fitting the MotoBox. Don't think i did anything as I was uber careful doing the job.

Have also recently fitted PCIII as well.

Any ideas welcome

1 long 7 quick is 17, rear 02 sensor. Make sure your eliminater plou is on corectly

no worries, i have this error after almost every good wash or rain... don't remember if i get 17 or 18, but it's always the plug by the rad, not the one in the belly pan. one day i'll put a condom on it...

Its def the rad side O2 plug. Had a fiddle yesterday and it seemed ok but then was out last night and it started again. Stopped and popped into a shop and when i came out and rode off it had stopped. Maybe its not liking all the room round because i have the MotoBox fitted
