The error codes you provided indicate several potential issues: - **2717 and 2716**: These codes often relate to the camshaft position sensor. A faulty sensor can cause poor fuel economy and trigger the check engine light. Inspect the sensor and its wiring for any damage or loose connections. - **27c3**: This code is related to the fuel pump or fuel system. Check the fuel pump and fuel filter for any blockages or malfunctions. - **279c**: This code typically points to a problem with the throttle position sensor. Inspect the sensor and ensure it's clean and properly connected. - **31, 3c, and 38**: These codes are less common but can relate to various transmission and engine control issues. It might be worth checking the transmission fluid level and condition, as well as inspecting the wiring and connections to the transmission control module. Start by addressing the camshaft position sensor and fuel system issues, as they are likely contributing to the poor fuel economy and warning lights. If the problem persists, consider consulting a professional mechanic for a thorough inspection. Let me know how it goes or if you have any further questions!
