ISSUE
Some 2003-2004 Crown Victoria/Grand Marquis and Town Car vehicles may exhibit a malfunction indicator light (MIL) with DTC P0442 (Evaporative Emission System Leak Detected (small leak)) in memory. This may be an erroneous DTC set due to a partial blockage (rather than a leak) of the fresh air vent hose connected to the canister vent valve. A spider nest may cause this blockage.
ACTION
Perform a smoke machine phase 1 - leak verification pressure test per the PC/ED. If a leak is indicated, proceed with normal leak detection diagnostics. If there is no leak indicated, remove and visually inspect the fresh air vent hose for a spider nest or other such blockage. Clear the hose by blowing out with compressed air and clear the DTC.

هذي مشكله تظهر لعدة اسباب .. من كلام المصنع انك تحتاج تنظيف فلتر الهوا والخرطوش الي رايح من الفلتر للمكينه وتفصل البطارية عشان تروح العلامة وتنحل المشكلة ... لاتنسى تشيك على اي تهريب للبنزين او تبخير من غطا للتانكي مثل ماذكر اخونا المارودر
موفق اخوي
