Code P1441

Question

We checked the gas cap as suggested. It looks ok and after clearing the code, I made sure the cap was securely on, so it is unlikely that the cap is the problem. I need a hint on where and how to check other things that it might be, such as where to check for leaks, a faulty cannister, and things of this nature.

HI there

This code is for a very small leak. It's difficult to find the leak without having a smoke test performed. The leak is a .05 inch hole some place. Since there are several possible causes, it's best to start with a smoke test. Here is a list of possible causes for this.
