It’s a sensor thing next to the gas tank pass side connected to a fuel line that runs towards the back of the car into a black box also pass side into which 2 or 3 other (fuel?) lines also run. What does this do and do I need it? Can someone tell me what the box is too?

Purple arrow is where it would be mounted ![http://i46.photobucket.com/albums/f133/thachoang/20140827_1045581_zps35e986bc.jpg](http://i46.photobucket.com/albums/f133/thachoang/20140827_1045581_zps35e986bc.jpg) This is the box, behind the rear pass wheel. Bottom of the pic is towards front of car[![http://i46.photobucket.com/albums/f133/thachoang/20140827_1045161_zpsd9bea092.jpg](http://i46.photobucket.com/albums/f133/thachoang/20140827_1045161_zpsd9bea092.jpg)](http://s46.photobucket.com/user/thachoang/media/20140827_1045161_zpsd9bea092.jpg.html) Was thinking box is a charcoal canister and sensor is a bypass solenoid kinda thing? ---

I never dug into that stuff on mine. It’s probably evap stuff. Scrape the dirt off and pull a part number off it. ---

People on buffalo scooby are saying check valve or purge valve or pressure sensor… idk. It broke off and idk how to reinstall. I think fuel will leak from that spot? A guy told me it won’t throw a code bc the sensor is just a two wire (he said even number wires: no codes, odd: codes. Is this true?). I’ll ziptie it onto the bracket and see how it goes Sent from my SGH-T999 using Tapatalk ---
