How can you repair the P1174 code?

The P1174 code typically indicates a problem related to the fuel system, often linked to a lean condition or issues with the fuel pressure sensor. To repair it, first, check for vacuum leaks, inspect the fuel lines for blockages or leaks, and ensure the fuel filter is clean. Additionally, test the fuel pressure and replace any faulty sensors or components, such as the fuel pump or regulator. Finally, clear the code and perform a test drive to see if it returns.
