GMC SIERRA ENGINE PROBLEM

2000 GMC Sierra • 195,000 miles

I had my truck scanned for a check engine and the code reads "p1441-Evap system Flow During non-Purge" I was wondering if this was a common code ad what the possibilities to fix it were.

I also have a ticking noise that is coming from the drivers side of the engine and was wonding if that was a vacuum leak, would it cause this code?

It is evap code. You need a scan tool. Smoke machine and voltmeter to determine the failure. The scan tool can activate the solenoids to make sure they are being commanded correctly and they are working.
