I got this error as both a confirmed and pending code.

I then found a small supply hose was disconnected and repaired it.

Now I see no pending codes but only the confirmed code.

Does that likely mean I fixed it but need x drive cycles to clear it?

It should go away once you clear the codes with the scanner. If not, it should clear after some drive cycles like you've stated.

I tried to clear the code right away... didn’t let me.

I drove a few trips today, getting over 50 mph each time then it let me clear the codes.

This simple repair also has seemed to fix a 3 year old issue with high fuel trim ratios!!!

Once I pushed the vacuum hose further into the valve nipple, I noticed a small crack in the hose.



I then pulled it back to disconnect it and glued the hose while propping it up on the disconnected end and allowed it to dry an hour.



Ever since, the fuel trim ratios are back to under 10% since being over 16-18% for many years. I will go back with a better epoxy to be sure, but this was a huge win.

I had the same challenge, thus glued as a short term fix while I searched. I gave up and have't had an issue since gluing it.

It’s just a vacuum hose. Any auto parts store will have one. Cut to length.

What is this "CHINA" tube or cable doing there?

Dogtag114

lol it's the paint brush I used to dab the glue on carefully. I used it to hold the hose up to apply pressure while it dried.
