What do these 2 codes mean, P1441 Evap Emission System flow during non-purge, p0441 Evap Emissions System no flow(During Purge). Yesterday I posted A possible fuel Problem, could any of these codes related to it, or at least be the reason my car wants to stall idle? Let me know Guys,

 

P0441 = EVAP vacuum switch circuit low during purge.

That means the purge solenoid is stuck closed. Might be a faulty solenoid, or it might be a solenoid plugged with carbon particles - but see the next one.

P1441 = EVAP vacuum switch circuit high during non-purge

That presents the conflicting indication that the EVAP solenoid is stuck open, and allow vacuum to reach the vacuum detector switch when the solenoid is supposed to be closed.

Is it possible you have the two hoses that run to the EVAP solenoid reversed? Possibly you have a screwed up purge vacuum switch.

 

It is possible that i do Have them reversed. It's maybe a simple Rookie mistake, I'm 19, and I did just install a whole engine harness by myself due to many burned sensors. Where are these vacuums located? Also, would these trouble codes cause a wierd idle and possible stalling? Thanks, You seem to have posted in all my Threads (injuneer)!

 

Okay, I scanned again, Only code is P1441. How can I fix this?

 

anyone???

 

The solenoid may be stuck open, or the switch could be bad. Pull the vacuum line off the solenoid and plug it up. If the switch is good, the light should go out.

Shoebox has al the info on the routing and the correct connections:
