What did this plug go to?

[Dnytro]

1996 Chevy c1500 5.0 runs perfect 140k original miles. I’ve had it for almost a month, it randomly gave me a p1441 code. I found a loose hose, replaced it, code hasn’t come back.

But I also found this plug just hanging out with nowhere to go. Any ideas? Could it have been 5.7 swapped and this was leftover?

Mystery solved. The purge vacuum diagnostic switch is missing.

Groovy! I was thinking A/C compressor! Glad you found it!

When it's a short run attached to the loom my 1st thought its within a small circle of possibilities.

Got that same code again, guess I gotta find this part and add it

I can’t find this part on amazon or rock auto, any help? 1996 Chevy Silverado 5.0

EVAP purge valve?

 

[Dnytro]

So my understanding is evap purge vale/solenoid is the part I have in the first picture I posted.

There’s a piece missing that I have a plug for that doesn’t have a home. That would be the purge vacuum diagnostic switch according to the emissions label. Using the below pictures I pulled off the Internet, I have the piece circled in red but I don’t have the part circled in blue, only the plug. And all the threads I found were dead ends, and I can’t find the actual part anywhere to purchase it.

Can you say "Treasure Yard"?

Sure. I knew you could.

Another option is to disable the reporting of the error, which can be done with a "tune" (one would need to check if P1441 specifically can be disabled). I used JET's tuning tools and I know there are a LOT of errors that can be "removed".

For example, I had a bad downstream O2 sensor that I needed some time to fix; I got tired of seeing the CEL so I disabled the reporting of the error by using the JET tool. Once I replaced the O2, I re-enabled the reporting. Easy peasy.

Well yea worse case scenario I’ll hit the junkyard. Which jet tool do u have, the performance programmer or the dynamic spectrum one?
