I have loaded the procedures to test the sensor from the book. If this is within spec than you would need to replace the module that runs the compass mini trip computer. Below are the steps to replace that as well only if the sensor tests good. Most of the time it is just the sensor or the wire going to the sensor but I have seen a few of the modules fail. Let me know if you have any questions and please take a moment to rate my service. Thanks.
