Welcome! My name is XXXXX XXXXX I will do my best to assist you with this problem.Ask me about added features such as phone contact anytime if you wish !
im sorry for the long wait did you still need help ?
yes i need help
do you have a multi meter on hand ?
once the codes are cleared how soon before they reset ?
if you do not have a multi meter we can trust that its 12 volts for now
if you jump # XXXXX to # XXXXX in the box with the relay out will the pump run ?
and will the air pump small solenoid turn on ?
ok at this point the truck will need to be plugged into a scan tool to further diagnose
lets see if any other expert have any quick tests you can do
hang on another expert will replay back to you
OK Have you cleared the codes after changing the one way valve?
At this point to do any further testing it will take a scanner capable of activating the air pump while watching the oxygen sensor. The sensor should got to below .300 when the air pump is running. It is a blind guess but you could try an new O2 sensor as that one could be getting "lazy". That is your call.

Thanks and have a great day,
Just found out that the system works only for the first 1 minute from the cold start point. everything works just fine but after that it seems like it only gets a tiny amount of voltage because the test light barely lights up a bit. is that normal?
Anyways, I just cleared the codes and Imma drive the truck for about 100, will see what happens. If CEL doesn't come back I'm taking it straight to do the smog test and let you know as well.
Appreciate your help!
No problem. It runs till the system goes into "closed loop" then it will run under certain conditions so I would say that is normal.
Yea give it a good run and see what happens.
Well, I've driven 150 miles and light hasn't came back. Guess we can call it a fixed now.
Thanks for the help, much appreciate it!
