Fuel Cap Warning Message: Notes
WARNING: This page is about a different car, the 2008 Honda Pilot, 2007 Honda Pilot, and 2006 Honda Pilot. However, it is still accessible from the selected car via links, so may be relevant.
The PCM detects whether the fuel fill cap is loose or missing under certain conditions, and alerts the driver by showing the information in the odometer/outside temperature display. If the PCM detects a small volume leak, the MIL may come on during the third drive cycle, and store a DTC.
