2103 tundra 2433 code?

I have replaced both of the compressors and the check valves but now have a 2433 and 2431 code. is the pressure sensor built into the injection valves?

 

The sensors are in the valves. The codes you have can be faulty sensors, problem with the harness or connection issue between the harness and valve

 

I figured that's where they were, i looked all over and couldn't find any in a line. When i first replaced that valve I had another code that popped up indicating an issue with that valve i disconnected it and reseated the connection after getting a little more slack in the wiring and that code went away but a couple days later it threw these new codes. Wondering if I have a bad Dorman valve or a bad connector.
