P00B0: Turbocharger/Supercharger Boost Control 'B' Module Performance

May trigger reduced engine power, poor boost response and limp mode

Overview

P00B0 OBD-II turbocharger/supercharger boost control B module performance fault

Common Symptoms

  • Check Engine Light (CEL) illuminated
  • Reduced engine power and boost
  • Poor acceleration or throttle response
  • Erratic or abnormal power levels
  • Vehicle may enter limp mode

Most Common Causes

Faulty boost control solenoid or actuator medium

Primary component controlled by PCM to regulate turbo/supercharger boost pressure

Wiring harness or connector issues medium

Heat and vibration prone circuits can short, open, or corrode

Exhaust leak affecting boost control low

Leaking exhaust before turbo may change pressure feedback

Internal PCM error low

Rare but possible if control logic fails

Diagnostic Steps

  1. Verify code with OBD-II scanner and record freeze frame data
    Expected: Code P00B0 present with relevant engine conditions
    Interpretation: Confirms repeatable fault before proceeding
  2. Visually inspect boost control solenoid/actuator and associated wiring for damage or corrosion
    Expected: No broken wires, connectors seated properly, no corrosion
    Interpretation: Visible damage directs repair to that component
  3. Test boost control solenoid/actuator operation and resistance per manufacturer specs
    Expected: Actuator moves and electrical values within spec
    Interpretation: Out-of-spec indicates solenoid/actuator replacement
  4. Inspect intake and exhaust system for leaks or restrictions affecting boost
    Expected: No boost leaks or exhaust leaks
    Interpretation: Leaks can cause erroneous boost control readings
  5. Check PCM for stored faults or communication errors
    Expected: No PCM internal fault
    Interpretation: PCM faults may require programming or replacement

Repair Solutions

Replace boost control solenoid/actuator medium
Estimated Cost: $150 - $600

Part cost varies by vehicle; labor required due to location near turbo

Repair or replace damaged wiring/connectors medium
Estimated Cost: $50 - $300

Scope depends on extent of wiring damage

Fix intake/exhaust leaks medium
Estimated Cost: $100 - $800

Cost varies based on leak location

PCM reprogram or replacement hard
Estimated Cost: $500 - $1500

Considered only if all other causes are ruled out

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Misreading related codes such as P00AF or other boost control circuits as the same issue
