As you drive and conditions allow, the engine computer (pcm) tests the evap system for leaks by monitoring pressure or vacuum inside the system The code p0442 indicates that the engine computer (pcm) has detected a small leak in the evap system With this code there might be no symptoms other than the check engine light.

The p0456 code indicates that your vehicle's onboard diagnostic system has detected a very small leak in the evap (evaporative emission control) system This system is crucial for controlling fuel vapors and preventing them from escaping into the atmosphere. Learn what the p0456 code means, common evap leak causes, and how to fix it
