    Code 34

    I've been getting error code 34 coming up when boosting the car (not all the time).

    Checked all VSV and vac lines and all seem good. The car has a boost controller fitted but it is not on.

    I went to my friends and using his Supra as a guide put all the vac lines back to stock and removed the solenoid for the boost controller. Still have the same issue.

    So decided to check the ECU and discovered my car doesn't have an FCD fitted (despite having a receipt for the part and for the fitting from the previous owner). I speak to him regularly and he was as shocked as me.

    I'm guessing/hoping the error code 34 is down to the stock boost cut? (Happens at around 15.8 psi which is essentially just over 1 bar) Car has double decat and a restrictor ring fitted.

    Does this sound about right? Should the car be running that much boost using the stock VSV's just from having decats?

    Thanks in advance!

    Normally you get a code 14 (ignition) if you've hit boost cut, not familiar with 34
    I would gladly pay you 10 to never log onto this forum again, and I am serious. Scott M

    Thank you.

    Found this in one of the threads

Hit 1.2bar then and recheck and it'll probably be back.

    Hoping I found the issue. Plug to the waste gate vsv had a broken wire. Could have been barely holding on and fully snapped when I removed the plug causing a dodgy connection? But hopefully that'll resolve it. Will go for a test drive in a bit!
