P2587 — Turbocharger Boost Control Position Sensor "B" Circuit Range/Performance

P2587 — Turbocharger Boost Control Position Sensor "B" Circuit Range/Performance. A fault in the turbocharger / supercharger boost control. Short, gentle driving to a shop is usually possible. Typical causes: worn turbocharger, vacuum or actuator line damage, faulty boost pressure sensor.

powertrain (engine/transmission)

Is it safe to drive?

Drive with caution Drive gently and avoid boost. The car will likely be down on power and may be in limp mode; ignoring boost faults can overheat the engine and destroy the turbo — a far more expensive repair.

How to diagnose with an OBD scanner

  1. Read the code and freeze frame Connect an OBD2 scanner, confirm P2587 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
  3. Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the turbocharger / supercharger boost control for damage, corrosion, chafing or poor contact.
  4. Subsystem check Compare the turbocharger boost control position sensor "B" live reading against a known-good reference (specification or a correlated sensor) under the conditions from the freeze frame.
  5. Subsystem check Pressure-test the intake piping for boost leaks — cracked intercooler hoses are the most common cause.
  6. Subsystem check Command the boost control solenoid with a scanner and verify wastegate movement.
  7. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2587 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2587 (parts and labor, USD, independent shop rates): Turbocharger replacement: $1,200–$3,500; Repair boost leak (hoses, clamps, intercooler): $100–$400; Replace boost control solenoid or actuator: $200–$600. Overall, fixing P2587 usually costs between $100 and $3,500. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

What does OBD2 code P2587 mean?

P2587 — Turbocharger Boost Control Position Sensor "B" Circuit Range/Performance. A fault in the turbocharger / supercharger boost control. Short, gentle driving to a shop is usually possible. Typical causes: worn turbocharger, vacuum or actuator line damage, faulty boost pressure sensor.

How much does it cost to fix P2587?

Turbocharger replacement — $1,200–$3,500; Repair boost leak (hoses, clamps, intercooler) — $100–$400; Replace boost control solenoid or actuator — $200–$600. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

What is the most common cause of P2587?

The most common causes are: worn turbocharger, vacuum or actuator line damage, faulty boost pressure sensor.

Will P2587 clear itself?

Sometimes P2587 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

Is it safe to drive with P2587?

Drive gently and avoid boost. The car will likely be down on power and may be in limp mode; ignoring boost faults can overheat the engine and destroy the turbo — a far more expensive repair.

What does P2587 mean?

When P2587 appears on a scan, it means the control module has flagged a problem in the turbocharger / supercharger boost control: turbocharger boost control position sensor "B" circuit range/performance. The fault sits in the powertrain (engine/transmission) group of the OBD2 standard.

“Range/performance” means the signal from the turbocharger boost control position sensor "B" is electrically valid but does not match what the module expects for current operating conditions. The wiring is usually intact; the problem is a degraded component, a drifted sensor or a mechanical fault upstream.

This code does not appear from a single bad reading: the module must see the fault condition repeat under defined operating conditions before it turns on the warning light. The freeze frame captured with P2587 — engine load, rpm, temperature, speed — tells you exactly when the problem occurs, so reproduce those conditions when testing.

What causes P2587?

  • degraded or drifting turbocharger boost control position sensor "B"
  • incorrect calibration after a module update or battery disconnect
  • mechanical fault that the sensor correctly reports
  • boost leak in intercooler piping or hoses
  • worn turbocharger
  • vacuum or actuator line damage
  • stuck wastegate or faulty boost control solenoid
  • faulty boost pressure sensor
  • clogged intake or exhaust (DPF/cat)

Common symptoms of P2587

  • Check Engine Light on
  • black smoke under acceleration
  • whistling or siren noise from the engine bay
  • limp-home mode
  • significant loss of power

How to diagnose P2587

  1. Connect an OBD2 scanner, confirm P2587 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
  3. Visually inspect the wiring harness and connectors related to the turbocharger / supercharger boost control for damage, corrosion, chafing or poor contact.
  4. Compare the turbocharger boost control position sensor "B" live reading against a known-good reference (specification or a correlated sensor) under the conditions from the freeze frame.
  5. Pressure-test the intake piping for boost leaks — cracked intercooler hoses are the most common cause.
  6. Command the boost control solenoid with a scanner and verify wastegate movement.
  7. Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2587 does not return.

How to fix P2587

Start with the cheapest and most common causes before replacing expensive parts:
