Re: P01456 Code Evap.

Most times, it's the cap though. Keep in mind that a rusty fuel tank won't throw a PO1456 code. But, those of us in the northern climates are used to rust, and we know what it effects.
I had the code for 3 years on Connie.

I noticed no difference after fixing it, aside from not having a CEL, and I drive Connie a LOT. I only changed the tank because it was becoming quite the leak and I needed to get some exhaust work involving welding done.

If you need to pass emissions, you still can without fixing anything; when you reset the code by unhooking the battery, it takes about 1/3 of a tank of gas for it to come back on. Your monitor for "evaporative emissions system" will scan as "not ready". You are allowed one "not ready" here in Ontario; as long as everything else comes back "ready", your overall result will still be a pass.
