P0455 and p0442


p0455-- emission control system ( a large leak ) the most common cause is a bad seal on fuel cap, remove and replace cap, if light stats on. replace cap. if not the cap it could be any where in emission system. p0442 is--same as above. Code p0442 indicates a fuel vapor leak in the EVAP control system. To fix this problem, remove and reinstall the gas cap. Clear the codes and drive to see if the codes reappear. If the code appears again replace the gas cap or inspect the system for cuts or holes in the tube or hose. good-day !

Error codes p0442 & P0455


Those are both Evaporative Emission Control System related.
442 is a small leak has been detected.
455 is a bigger leak has been detected.
Check all your connections, (electrical & vacuum lines) as well as check for any cracked, loose vacuum hoses in the system, as well as clean "O" ring on your gas cap well and threads in filler pipe & make sure gas cap is tight. Do the gas cap first & see if codes dissappear, but it may take a new gas cap. These codes commonly appear shortly after getting gas, due to cap not back on tight.
