manifold absolute pressure CEL code #106

[lilbayz311]

ever since i first turboed my car i haven't been able to get rid of this code. i have had both the hahn racecraft fuel cut defender mod that isnt that reliable, and i currently have the missing link installed, which does not allow my map sensor to read pressure, instead it opens it up to the atmosphere through this little air filter. it is a badass little valve but it never got rid of this annoying code. (I also tried at the same time a new map sensor) i have sent my ecu in one time when i couldn't figure out why my car wasn't starting after replacing the pistons and supposably they fixed anything that may have been wrong with my ecu. that turned out to not be the reason it wasnt starting anyways, but my ecu should be good. i can clear the code and start my car soon thereafter, and it will run will no CEL until i shut my car off and start it again it is always back on. i can clear the code and wait 5 minutes to start my car and by that time the CEL will already be on even though i just cleared it 5 mins ago and just barely turned it on. ive been having this problem for over a year now does anybody have any suggestions?

You could try a better FCD than the one Hahn sells.

they actually include one with the turbo kit package. i tried it and it still threw the code. the missing link is better. am i the only n/t turbo conversion that consistantly has this check engine code that wont go away?

I know they do; but it's had a history of inconsistent quality. The same goes for the missing link, which is often prone to mechanical failure. A better FCD should do the trick. Search for "420A FCD" on Google; the first page of hits has a couple of good results.

I have an afc neo which reads airflow aka what the map sensor is putting out. when i had the fuel cut defender it would consistently break way over what a non turbo car's airflow should be. with my fuel cut defender, seems how it is just a valve, it has never broke that limit. it will go to slightly over 4 airflow and no more. it has never shown more since i installed that valve. i honestly dont think that is my solution. i have heard only good things about the missing link until now
