S-Mode Warning Light/Beep (09' 370z Sport)
 

I have not driven the car much this year and have noticed S-Mode no longer comes on. I hold the button in neutral and I get a beep and a warning label on the dash. I have no had any issues with it before now. I was looking online and saw that the clutch sensors may be out of whack? I did put in a RJM pedal over a year ago with no problems. I plan to look at the sensors that are mounted to the pedal, but am wondering if there is anything else to look into as well. Thanks.
