I was using my 2006 T190 SJC controls and the warning horn sounded twice and in the right side control panel shows a "!" and the snail logo. When I check the panel for the active warning it says "Right side drive speed sensor out of range high". The T190 seems to run fine. If I keep using it will it do any damage to the machine? I can not read the code that would be on the left panel because half the LCD display panel is out. I did check the codes on the stored section of the deluxe control panel in the owners section but no stored code there. does this mean the sensor is bad or is there another cause. Is there a way to test the sensor or does it just need to be replaced.
