A scan tool should take care of this. Be aware that clearing the code does not fix the issue. Here are some code readers we recommend: https://cartreatments.com/best-automotive-scan-tool/

Thank you for the advice, and just to let u know I did first check the smallest less expensive possible causes & or problems, and because I have the worst luck, of course it wasnt anything cheap and simple, no my truck is 22 years old & a temperamental beast but I love my toyota, & honestly shes never left me stranded until recently but I’ve done mostly everything so I know there cant be to much more to fix or get fixed on her. Just wish for once itd be a cheap fix instead of the highest priced part on her. I have looked around & called several places in and around the area I live in, I dont trust any of them honestly cause in 1 way or another they are out to make money & usually females dont know a whole lot about vehicles except this 1, I have lived and learned & still learning but hopefully by the time I’m done with this truck, I’ll be able to open my own shop & fixed not just my vehicle but many others as well & make a little money doing it, but I wont be **** hard working people that just need their vehicles fixed not tons of other **** they dont need.
I thank you again & maybe I can ask u what u think the next time I run into an issue or another problem with my toyota if that’s ok with u.

Sincerely,

The amount of DIY work you’ve done on your rig is admirable! I think you may save money in the long run by bringing your vehicle to an independent mechanic for a formal diagnosis. Independent mechanics are almost always cheaper than dealerships. Ask around for trustworthy shops in your area.

After the shop diagnoses the issue, they don’t have to replace the part if you don’t want them to, but having that professional diagnosis may end up being cheaper and less frustrating than throwing parts at the problem. It could be a simple fix such as an O2 sensor, open circuit, clogged hose, etc. If this is the case and you fix it yourself, it’ll probably only cost you a few bucks over the diagnostic price, which ranges from $100-300 depending on how in-depth they go.

If you have the time and the patience, you could also read through the fuel system section of the factory manual like a novel and perform the diagnosis yourself using the recommended procedures. It’ll take quite a while to learn the ins and outs of the system (it’s pretty complicated), but you’ll save even more money that way.

Thank you very much, I appreciate all the comments that I can get in response to fixing my purple beast.
