Customer Question

I have a 01 Toyota Avalon xls with a c1301 and p0441 codes. What causes this and what is needed to fix?

The 1301 code is a byproduct of the p0441. You have to start by diagnosing that.

Is the gascap loose?

Do you have a scanner, so you can active test the vsv's?

Gas cap was replaced. Isnt there a tsb on these 2 codes showing up together?
Expert:  Jason replied 6 years ago.
Yes, the 1301 is a byproduct of the p0441 code. Once you diagnose and repair the 441 code. the 1301 just has to be cleared.
Customer: replied 6 years ago.
Will see if replacing the cap takes care of it. Do you have a copy of the tsb?
Expert:  Jason replied 6 years ago.
I don't think the gascap is causing the problem, It most likely has a faulty switching valve. It has to be diagnosed. That is not something that can be done via internet.
