Electric Turbocharger/E-Compressor Motor Fault

on 2020 Dodge Challenger 6.2L V8 Hellcat (707hp) · RWD

What this code means

The electric turbocharger or electric compressor motor has an electrical fault. E-turbos eliminate turbo lag by using an electric motor to spool the compressor.

Symptoms

  • Check Engine Light
  • Turbo lag returns (no electric assist)
  • Reduced low-RPM torque
  • 48V system warning may accompany
  • E-compressor noise absent
  • Slower throttle response

Common causes

  • E-compressor motor winding failure
  • Inverter circuit fault
  • 48V power supply insufficient
  • Motor bearing failure
  • Overtemperature shutdown

Diagnostic steps

  1. Read e-compressor fault codes
  2. Check 48V supply to e-compressor
  3. Test motor phase resistance
  4. Monitor motor temperature
  5. Command e-compressor operation via scan tool

Repair notes

Replace e-compressor motor or inverter assembly. Check 48V system health. These are typically found on 48V mild hybrid systems.
