What Does OBD2 Code P1401 Mean for a 2000 Hyundai Accent?
I'm looking for information on what OBD2 diagnostic code P1401 means specifically for my 2000 Hyundai Accent. Can anyone explain the meaning of this code and what steps I should take to diagnose or fix it? Thank you.
DTC P1401 indicates an EVAP system leak detected by the diagnostic module. This is a fuel vapor emission system malfunction. A smoke test is typically required to locate the exact source of the leak. Always check that the gas cap is securely tightened first, as a loose cap can trigger this code.
