During the diagnosis the Leak Detection Pump<br />

(LDP) -144- creates a pressure of 30 mbar in the<br />

EVAP system. When the pressure is attained the<br />

pump switches off. If the pressure drops below a<br />

predetermined value the pump switches on<br />

again. The self-diagnosis monitors the switching<br />

periods and sets a code in the Diagnostic<br />

Trouble Code (DTC) memory when the period is<br />

too short.<br />
