Most vehicles will have some EVAP issues over their lifetimes, but the Honda Pilot is typically on another level. From time to time, You'll be met with a C-HRistmas-tree like array of dash lights, and an even more vast library of OBD-II fault codes. The most common emissions system issue on the Honda Pilot is medium EVAP leak, caused by a corroded fuel filler neck. Of course, it's possible that Your error will be because of a loose gas cap, so it's worth checking that first. If Your fuel filler neck is still intact, You should look to Your purge canister; this is another common component to do. The top of the fuel tank is also known to corrode, especially in climates that necessitate the use of a fair amount of road salt.

The signs of the pollution system have one commonality that will almost always be present. The engine light will illuminate and the codes will be stored in the powertrain control module (pcm) alerting the driver to the existence of an emission problem. In addition to this slight commonality, emission system failures have limitless symptoms that may occur because the emission system is related to everything the engine and transmission does, as well as to all its accessory symptoms. It means that the vehicle could show symptoms such as hesitating, hesitating, failing to move properly, failing to start, stalling, rough idleness, and the list could go on.
