Most vehicles may experience EVAP system problems at some point, but the Honda Pilot tends to have more persistent issues. Occasionally, you may encounter a cluster of dashboard warning lights resembling a Christmas tree, along with a wide range of OBD-II fault codes. A prevalent emissions problem in the Honda Pilot is a medium EVAP leak, often due to a corroded fuel filler neck. However, it's essential to first check for a loose gas cap as that could also trigger the error. If the fuel filler neck is in good condition, inspect the purge canister, as it is another common culprit. Additionally, the top of the fuel tank is susceptible to corrosion, especially in regions where road salt is heavily used.

In most cases, when there is a problem with the pollution system, the engine light will turn on, and codes will be saved in the powertrain control module (PCM) to let the driver know about an emission issue. Apart from this typical sign, there are numerous symptoms of emission system failures since it is connected to all engine and transmission functions, as well as accessory operations. This means the vehicle may exhibit issues like hesitation, difficulty moving, trouble starting, stalling, rough idling, and more.
