A little background first. Rode down to Daytona last Thursday. Everything was fine. Even noticed I got around 50 MPG out of one tank of constant highway droning. Friday, riding back to the hotel from Destination Daytona I thought the bike sounded slightly different but it seemed to ride the same. After stopping, my wife even commented that it sounded a little different to her. Returning home on Sunday, my mileage dropped into the mid to high 30's for several consecutive tanks. Got in from work this morning, washed the road trip grime off the bike and decided to check for DTC's. I'm getting a P0152 - Rear Oxygen Sensor High. Also getting a 61008 under the SP module but I can't find what that is. Searching this forum leads me to believe I have a faulty sensor or bad wiring to the sensor. Does this diagnosis match my symptoms? Anyone know what the 61008 is? Bike is still under warranty but is this something easy for me to do if it's a bad sensor? Thanks!!
