Guest BillAdams Report post Posted October 29, 2010 In short, this is a pretty common occurrence. "Stuff", especially TP, gets stuck to the sensors and the tank walls and give false readings. You will learn how long you can go without dumping and just make this a regular routine no matter what the sensors read. There are after-market options that can be installed that are more accurate than the factory units but none of them are perfect. Sit, relax and enjoy. Just don't wait too long or you will be in for a rude surprise! Share this post Link to post Share on other sites
