Check Engine Light, What to do?

Two days ago I got a check engine light and when I scanned it the code was P2445, I erased that code earlier today to see if it will come back, I’ve been driving it all day and it has been working perfect but about ten minutes ago I got another check engine light with the codes P0418, P2445, P0418 pending, P2441 pending and P2445 pending. I’m just not sure what I need to replace. If anyone can help with this that would be appreciated. Thank you!

 

4-cylinder? https://www.tacomaworld.com/threads/2006-tacoma-2-7-2wd-p2441-p2445-codes-anyone-fixed.384766/

It's a failure-prone system because it's exposed to exhaust gases and soot.

 

Yes it’s a 4 cylinder. So would you recommend me getting this? https://ebayvehicle.com/app/VKzg

 

^Bad pump is one of the possibilities. However, the problem could be in the switching valve or wiring:

P0418 is a circuit code, "Secondary Air Injection System Control 'A' Circuit."
P2441 is "Secondary Air Injection System Switching Valve Stuck Close Bank1"
P2445 is "Secondary Air Injection System Pump Stuck Off Bank1"

Do a visual inspection for a detached or cracked hose. If none found, take it to a shop. With a good scan tool they can do system tests to better isolate the faulty part. It needs to be diagnosed properly or you'd waste money throwing parts at it.
