P2443 – Secondary Air Injection System Switching Valve Stuck Closed Bank #2

Hey all , I'm getting that P2443 code , and was wondering if anybody tried using that Hewitt Technologies Secondary Air Injection bypass kit ?

Any input much appreciated - thanks

 

That is a good one. It has been used by many on this forum and are pleased with it.

 

Thanks ! The truck is running fine , but being I live in f'n rip-off New York , I really just need it for emissions .

 

Late on the thread but I put it on mine about 5 years ago. Works great

 

It can be put in after the AIPs fail? Mine are running great still, never been replaced, but I always dread the day.

Maybe being in an semi-arid/hot environment keeps them working well.

 

Yep. My secondary pump failed. Was told to replace both primary and secondary but was a stupid expensive job. Grabbed the kit for $300. Easy fix. About an hour and half job. Basically treat the startup of the truck now like a diesel so the computer gets the read on the air.
