Default Code 34

34 Turbocharger Pressure Diagnosis
  • The turbocharger pressure is abnormal.
Trouble Area
  • Turbocharger
  • Air flow meter
  • ECU
  • Intercooler system

Right so i got this code after doing a pull to 100mph. I guess i hit fuel cut? or is this something else. Have a 1/4" spacer on the actuator

Too high boost pressure due to a disabled waste gate could definetly cause this code. I would reset and not worry about it, unless it comes back, then take out your spacers and see if it comes back a third time, if it does, then worry about it.

Until then have fun with the 12psi!
