My 97 Toyota 4 runner had an issue with the check engine light coming on. I checked it out and it was code P0441 - Evaporative Emission System Incorrect Purge Flow. I looked it up and found it could be caused by a few different things, but one of them mentioned possibly your gas cap is not on tight enough, or is bad and not working correctly. Fails to open or close properly. I checked mine out and it was pretty corroded on the inside. Mine was not a factory OEM model, but had been replaced before. So I ordered a new one off of Amazon.
This is the 97 4runner gas cap I ordered from Amazon:
The model number I purchased is #77310-35080
I did find online that after 3/98 it looks like they switched to part number 77310-48020. Looking at the pictures this new model has some added print on the gas cap. It mentions to tighten until clicks or malfunction indicator may come on. Not sure if the rest of the gas cap is the same, or if that was the only change.
Here is a link to an OBD II code reader kinda like the one I had in the video :
I did not see my model online, maybe I got it at harbor freight or something. But mine was in the same price range as the link above I think, ~20 bucks.
Hope someone finds the video helpful.
