I started up Holga the other morning, checked the range on the OBC, and got ----M flashing. Strange, I thought, but I had just gotten gas, so maybe it was still chewing on the input... I pulled out of the driveway, and noticed shortly after the speedo was de-funked. MPG gage dead, range... function kaput. Someone please tell me that I have not lost a sensor on the flywheel... I want it to be something simpler. Any thoughts Y'all??? As always, I appreciate it!!!
