P0045 — Turbocharger boost control circuit

Severity: Attenzione Can you drive? With caution: limp mode possible, have it checked soon Produttore: Tutti makes (OBD-II standard)
MeaningThe circuit controlling the turbo's variable geometry is not responding as expected. The fault is electrical oppure pneumatic, not necessarily in the turbine itself.
FamilyPowertrain (P)

Typical symptoms

Reduced Potenza
Motore Attenzione light on
Slow oppure absent turbo response

Common causes

Faulty control solenoid
Disconnesso or cracked vacuum pipe
Seized Elettrico actuator
Broken wiring

What a do

Usually an inexpensive repair: solenoid, pipe oppure actuator. It is worth cleaning the variable geometry as well, since the actuator often Fallita while forcing against carbon build-up.
