If you have a check engine light on, have the codes read. It may be as simple as replacing the fuel cap.
Trouble code P0446 means: EVAP Vent System Performance
Trouble Code P1457 means:Evaporative emissions EVAP control system leakage So to fix it you need to replace the EVAP Canister
For sure you can You need to have the evap system inspected. It may be as simple as replacing the fuel cap.
To fix an EVAP leak in a 2001 MPV, start by inspecting the EVAP system components, including the gas cap, hoses, and the charcoal canister for cracks or damage. Ensure that the gas cap is tightened properly, as a loose cap can trigger leaks. If the problem persists, use a smoke machine to detect leaks in the system, then replace any faulty parts as necessary. Finally, reset the check engine light and perform a leak test to confirm the repair was successful.
To fix an EVAP issue in a 2002 Toyota Solara, first, use an OBD-II scanner to identify specific error codes related to the evaporative system. Common fixes may include replacing a faulty gas cap, repairing or replacing damaged hoses, or addressing issues with the EVAP canister or purge valve. After repairs, clear the codes and perform a drive cycle to ensure the system is functioning properly. If the problem persists, consider consulting a professional mechanic for more in-depth diagnostics.
Code P1450 often indicates an issue with the evaporative emission control system, specifically related to the pressure sensor or the purge valve. To fix the problem, you may need to replace the evaporative emission (EVAP) pressure sensor or the purge control valve, depending on which component is malfunctioning. Additionally, inspecting and repairing any vacuum leaks in the EVAP system could also be necessary. Always consult the vehicle’s service manual for specific diagnostic and repair procedures.

If a smog inspector said that the EGR EVAP and Fuel Pressure sensor are modified on a 1988 Isuzu Trooper II 2.6, then the problem has to be fixed before the smog inspector will approve the vehicle for registration. The EGR EVAP and Fuel Pressure Sensors have to be put back the way they came from the factory.
Remove the dash and replace the evaporator...you might as well replace the heater core while your in there. Its a big job...but can be done a lot cheaper than bringing it to a mechanic
Trouble code P0446 on a 1995 Toyota pickup typically indicates a problem with the evaporative emission control system (EVAP), specifically the vent control circuit. To fix this issue, first, inspect the EVAP system for any damaged hoses or connections. Next, check the function of the vent valve and replace it if necessary. Finally, clear the trouble code and monitor for reoccurrence to ensure the issue is resolved.
To fix a P442A EVAP code, start by inspecting the EVAP system for any visible leaks, especially in the gas cap, hoses, and connections. Check the gas cap for proper sealing and ensure it’s tightened or replaced if damaged. Next, test the EVAP purge and vent valves for functionality, and consider using a smoke machine to detect leaks in the system. If necessary, clear the code with an OBD-II scanner and monitor for any reoccurrence after repairs.
Check for vacuum leaks and good electrical connection at the EVAP vent solenoid
