Fuel Cap Warning Message
Fuel Cap Warning MessageThe ECM/PCM will detect a loose or missing fuel fill cap as an evaporative system leak and alerts the driver by showing a warning message in the gauge display.
The first time a leak is detected, a CHECK FUEL CAP message appears on the gauge display (A). To scroll to another message, press the select/reset button. The CHECK FUEL CAP message will appear each time you restart the engine until the system turns the message off. Turn the engine off, then replace or tighten the fuel fill cap until it clicks at least once.
