GDI Piezoelectric Injector Driver Circuit Fault

on 2017 Maserati Levante 3.0L V6 Twin Turbo · AWD

What this code means

The piezoelectric fuel injector driver circuit has a fault. Piezo injectors use crystal stack expansion for ultra-fast, precise fuel delivery in advanced GDI systems.

Symptoms

  • Check Engine Light
  • Misfire on affected cylinder
  • Rough idle
  • Reduced power
  • Fuel smell from exhaust
  • Catalyst damage risk if prolonged

Common causes

  • Piezo driver circuit failure in PCM
  • Injector piezo stack degradation
  • Wiring open or short to injector
  • Connector pin corrosion
  • Injector capacitance out of range

Diagnostic steps

  1. Test injector capacitance with specialized tool
  2. Check driver circuit output waveform
  3. Measure injector wiring resistance
  4. Inspect connector for corrosion
  5. Swap injectors between cylinders to confirm

Repair notes

Replace piezoelectric injector. PCM replacement if driver circuit is faulty. Piezo injectors require specialized diagnostic equipment and are not interchangeable with solenoid-type GDI injectors.
