19/44 Evap Peake Code wont go away

[dcaron9999]

Hi guys.

Should I assume an electrical problem with my EVAP valve on my 2002 330xi, with the following symptom? I cant clear the specific (19/44) Peake code, but I am able to do so for other codes. The 19/44 code comes back immediately, without even starting the engine. The car drives perfectly, idles perfectly, has decent fuel consumption, etc.

I haven't tested/observed the valve up close yet...

The Peake Code translates to "Evaporative emission system purge control valve"

Thanks.

Today, I had a chance to use contact cleaner on the electrical connection on the PCV. I also measured resistance across the two leads, and measured 270 Ohms. After I did this, I was able to clear the 19-44 code for the 1st time. Drove the car a bit, and the Check Engine light returned, which turned out to be the same Peake Code again.

I will try a last attempt to completely remove the valve from the car this time around, to get better access to it, clean properly, and test it with a 12 volt source.

I think your vacuum valve circuit is most likely shorting out or is no longer working. I believe a new one is around a 100 bucks if jumping it/cleaning it doesn't work again.

Update:
Here's a list of things I did to my EVAP valve today, which allowed me to clear the 19-44 code. It seems like I have an electrical connection issue.

Here's what I did:
dismounted the evap valve.
cleaned the two vaccum ports with brake cleaner spray.
scraped the connection pins with a tiny screw driver, to expose metal.
sprayed the pins with electronic contact cleaner.
remounted valve.
cleared the codes.

PS: I could not clear the codes with the Peake Research tool until I cleaned the EVAP valve metal contacts.

Let's see if she holds ...

Update on EVAP code. A couple of days have passed, and the code hasn't re-appeared. It seems like my EVAP valve had "dirty" electrical contacts to begin with.

good stuff man
