P0756 and P0014 Fault Codes - 2004 GMC Envoy | Check Engine Light & Fuel Gauge Issues

Model: 2004 GMC Envoy Fault Code: P0014 Posted: 2016-01-05 16:58

Today while driving on the highway, my 2004 GMC Envoy suddenly triggered the check engine light and fuel gauge icon. The fuel gauge initially dropped to zero, then fluctuated between zero and full readings. Using an OBD2 scanner, I retrieved fault codes P0756 and P0014. I'm looking for clarification on what components might need replacement or repair to resolve these issues. Can anyone provide insight into the likely causes and recommended fixes for this combination of codes in a 2004 GMC Envoy?
