The valves are located under the intake in the back but I think you might be able to get to the connectors. I would start by taking a look around there for rodent damage, they love that part of the intake.

I should also note that truck won't idle on its own either. Idk if that the valves would cause this as well?

Sounds like you have a separate issue to me. The mass airflow sensor bad?

I have a similar question but did not want to start a new thread. If this offends the OP, I will be happy start another...

At just under 80k my 2007 SR5 5.7 CM truck went into limp mode and the EPA BS induction pumps and valves needed changed. I have been reading about the DIY bypass and another person who sells PnP bypass kits on eBay. I tried one of the Ebay kits but the dashboard lights up like a Christmas tree! (traction control, 4Lo, check engine, etc.) I get a CEL of mass airflow sensor. I unplug, clear the codes and truck starts and runs fine. Plug the bypass back into the sensor and same thing happens and doesn’t want to run.

As I continue to do reading, it appears that the dealership not only replaces the pumps and valves but also reflashes the ECU, making the DIY bypass option not work. Is this correct?!? Is there now no way to disable this system or is another fix available?

My pumps and valves are working correctly, but I want to disable this system and never have to worry about this again. Any options?

Thanks for the input guys.
