P2433 code limp mode help

Okay new here. Got my 08 5.7 tundra about 4 months ago and was running great no issues until about 3 months ago when it was trying to start and just wouldn't fire up I noticed something that was cover with gunk and buried in the motor that just didn't look right (the pressure sensor) and once I cleaned it, it fired right up. Seemed to have went away but now every once in awhile it will take a second to actually fire it will turn for like 5 seconds then fire up. Today my truck went into limp mode and the code p2433 came up. Do not know a whole lot when it comes to mechanical issues etc.. I was reading up on the whole air injection bypass etc.. and I looked and my truck has that. Not really sure where to go from here. I did notice today that the right side of the secondary air injection does not have anything plugged into it. I'm assuming it's not needed cause the bypass? I may or may not be making sense with all this but if I am, any help would be much appreciated.

Also, I have been reading on here others with this issue and I see people say get the bypass which I already have. Which is why I'm making this post.

 

If you don't require inspection do the bypass. If the bypass has issues then contact them for assistance

 

I already have the bypass. I did reach out to them. Just curious if anyone else ran into this situation.

 

There have bern a few posts with issues that are resolved by contacting the company
