Default What is this??

I have a code showing 0441 Evap system no purge flow, As I was looking around the Evap system I came accross this hose under my solenoid I dont see anywhere it would connect to and dont even know if it would connect to anything, Does anyone know what this is and if it connects to something? Maybe it could be causing the code???

you cut off the URL for the pics.. but. what I think that yur talking about is teh purge sensor. should be in line with teh selinoid and detects flow. Has 3 vac ports one of which is a vent to atmospehere which is probably what your seeing.

yup, thats the flow sensor. It's normal. Thats how it should be. clear the code and see if it returns. if it does there are some things that I can tell you to check.

I pulled out the solenoid and found some charcoal in it, I cleaned it all out and am going to pull the canister off tomorrow and check the filter. Also went over to autozone a cleared the code hopefully it doesnt come back. Thanks HBH

Hey, if the selinoid has charchol in it then the canister is toast. you need to replace that, the selinoid, (possibly) the flow sensor and flush the lines out with compressed air. The selinoid doesn't take kindly to the charchol at all. Good luck and lemme know if you need anything.



as for the switch, they are all custom made per your spec so they take a couple of days. I don't have any orderds now so it would be done fast. the website is being updated so shoot me an email and I'll work everything out with you. sales@hbhracing.com or hbhracing@yahoo.com


good luck
