To test code P1491, which typically pertains to an issue with the evaporative emission control system, you should start by using an OBD-II scanner to confirm the code and check for related codes. Next, inspect the EVAP system components, including the gas cap, hoses, and valves for leaks or damage. Perform a smoke test to identify any leaks in the system. Finally, clear the code, run the vehicle through a drive cycle, and recheck for any codes to ensure the issue is resolved.
