Turbo/Supercharger Boost Control Circuit Low

on 2005 Dodge Ram 1500 4.7L V8 · 4WD

What this code means

The signal from the turbo boost control solenoid circuit is below the expected threshold. This prevents proper boost pressure regulation.

Symptoms

  • Check Engine Light
  • Underboost condition
  • Sluggish acceleration
  • Limp mode activation
  • Excessive turbo lag

Common causes

  • Short to ground in boost solenoid circuit
  • Faulty boost control solenoid
  • Corroded wiring connector
  • Failed turbo wastegate actuator
  • Low system voltage

Diagnostic steps

  1. Measure voltage at boost control solenoid connector
  2. Inspect wiring for shorts to ground
  3. Test solenoid coil resistance
  4. Check wastegate actuator rod movement
  5. Verify battery voltage and PCM ground

Repair notes

Repair short circuit or replace boost control solenoid. Check wastegate linkage for binding.
