Secondary injection - incorrect flow saga (still unsolved) ...

Well, checked for hose integrity, replaced the combi-valve and relay, took out the solenoid and pressure tested it with it on and off, ran the output tests for solenoid and air pump; all are fine. With the output tests, I can hear the solenoid, relay and air pump operate. I'm still getting this annoying 16795 incorrect secondary air flow code.

Can anyone suggest something else that I should try. This issue is driving me nuts as I've trying to resolve for the last 8 months. My mechanic has no clue either.

Thanks in advance,

Henry

you must be leaking vacuum somewhere

make sure the vacuum lines to the combi valves are not cracked and leaking.

the only other possibility is some sort of cat/o2 sensor problem.

it sounds like you checked the integrity of the rest of the system pretty well.

I did pressure check the braided line ...

that goes from the solenoid to the combi-valve with a vacuum pump up to 25psi and no leak. Other lines I visually checked. Sigh...
