FOBO 2 Front Tire Sensor Reading Way Too High

Hello, my Fobo2 bike front sensor is reading over 100PSI while the bike tire is 34psi. I confirmed with the other sensor and multiple tire gages. I can't get the front tire sensor to read correctly. I've tried a firmware update, reinstalling it several times, and pulling out the battery and then putting it back in. How do I get the sensor to read correctly? Thx! Ralph
