The error codes 003f30, 004302
The error code 003f30 typically relates to the fuel rail pressure sensor, while 004302 can indicate an issue with the fuel system. Start by inspecting the fuel rail pressure sensor for any visible damage or loose connections. If everything looks fine, consider cleaning the sensor and checking the wiring for any signs of wear or damage. If the problem persists, it might be necessary to replace the sensor. Let us know how it goes or if you have any further questions!

Start by checking for any stored error codes using an OBD-II scanner. This will help confirm if the rail pressure sensor is the issue or if there's another underlying problem. Let us know what codes you find, and we can guide you further.
