code 34 turbo pressure signal


does this mean a vacuum line is loose or a bad component?

my car now sputters when i get on the boost even a little bit.

this problem happened overnight and i checked all the vacuum lines and cant find any out of place.

my car ran great before and boosted fine up to 10psi or fuel cut.

i would like to fix this asap because i am currently job hunting and this my DD. Any input or things i should check? thanks

You have a boost leak. Same code, same symptoms as when it hit fuel cut before. Ponimau?

thank you for the reply. A supra buddy sent me some good links and i didnt know this could also be caused by hitting fuel cut. I havent dumped my codes in a while so i bet code 34 is from a while back when i hit fuel cut. I will run the car tomorrow and check for new codes and double check my intake piping. The sputter i wrote about really reminds me of a bad fuel pump so i will also check that.


Ponimau=Ponimayu?

You appear a little confused. Fuel cut will set 34 and your code may well be old but the symptoms you describe indicate a boost leak you now have, something that will also set 34. Or maybe I'm the one confused. Either way best thing to do is what you said: clear the code and drive the car again. If the code returns you need to inspect the intake tract for leaks.

Ponimau=Ponimayu?

Yes, although "ponimaesh" would be more correct. It slipped out. What happens when you're married to one. I need to use the word often
