secondary air control valve problems

I have seen this thread, and about ready to spend 900 on parts from Toyota I put the b bank switching valve in from an aftermarket and the lights did not got away. I have a hard time believing the oem parts will perform any better. question -if I do this will the codes go away automatically or do I need to go back to Toyota to have them erase them?

 

Get a $20 code reader from Amazon or go to auto parts store and have them reset the codes.

However, most people will take advantage of the Hewitt bypass kit instead of fixing that system.

 

Here’s a good thread on the subject that discusses a couple options. Search the forums for AIP or Hewitt and you will find many more. https://www.tundras.com/threads/secondary-air-injection-valve-aip.28797/


Can also make your own for $20 if your good with wiring.
