Sorry to be a pita but did you swap the electric plug and the vacuum hose?
If you want to physically test the sensors with a DVOM then I suggest you read my early contribution here as the YFSM is NOT correct:My next course of action was going to be the diagnostics mode for the individual sensors.
Yep I'll check for sensor damage....didn't even think of that....duh.
🤦♂️hahaha ok I'm a knuckle head!! I knew I was missing something completely obvious lol! Yes one of the Vacuum hoses seemed to be slipping off the sensor each time I put it back on and would fire the bike back up. Its loose on the sensor and must of been vibrating just off of the sensor while the bike fired up. One small tie wrap and problem solved! lol Thanks for working through this with me fellas, even though I'm a numpty haha! Lesson learned!
