P132B — Turbocharger/Supercharger Boost Control A Performance — 6.7 Powerstroke

Diagnostic reference for P132B on 6.7 Powerstroke (2011–present).

Updated October 15, 2026

What it means

Ford enhanced code: the VGT boost control is not achieving the commanded boost.1

Most likely causes

  1. Boost leaks in the charge-air system (intercooler boots, CAC pipes, clamps). — Leaks reduce measured boost relative to command and are a common first check on the 6.7L Power Stroke.123
  2. Sticking or sooted VGT vanes. — Carbon/soot buildup causes vane position error and poor boost tracking.124
  3. VGT actuator or control fault. — Actuator response or position feedback error prevents achieving commanded vane position.124
  4. MAP/boost sensor or sensing error. — Incorrect manifold pressure feedback makes commanded vs actual boost appear mismatched.124
  5. Restricted intake/air filter. — High intake restriction limits achievable boost under load.3

How to diagnose

  1. Verify freeze-frame conditions and confirm P132B is present with no other turbo-related codes active.
  2. Inspect charge-air system for leaks: intercooler boots, CAC pipes, clamps, and connections; look for oil residue or loose fittings.
  3. Check intake restriction and air filter condition.
  4. Review live data: desired vs actual boost, VGT vane commanded vs actual position, and MAP sensor readings under steady load.
  5. Command VGT vane sweep with a scan tool and observe actuator response and position feedback for sticking or slow movement.
  6. Inspect turbocharger for excessive shaft play, oil contamination, and signs of vane sooting; evaluate need for cleaning or service.
  7. Test MAP/boost sensor supply, ground, and signal integrity; compare to a known-good reference or substitute sensor.
  8. Clear codes and road test under load to confirm boost tracks command within specification.

Common mistake to avoid

Replacing the turbo before smoke-testing the intake. Boost leaks at intercooler boots, end tanks and clamps are a common cause of low power and underboost codes, and they mimic a failing turbo. Source: BD Diesel — 6.7L Power Stroke problems and real fixes.

Parts and tools you may need

Tools you’ll need

Rough cost and difficulty

Likely repairPartsShop laborWho usually does it
MAP/boost pressure sensor$40–$2000.3–1 hrsEasy DIY
Intercooler boot, clamp or pipe repair$20–$2000.5–2 hrsEasy DIY
Electronic VGT actuator$400–$9001–3 hrsDIY with tools and a manual

Typical US independent-shop figures; labor runs about $120–$180 per hour (dealers charge more). Confirm the diagnosis before buying parts.

When to see a pro

If VGT actuator calibration, turbo removal, or internal cleaning is required, have a qualified diesel technician perform the work.

Check for recalls

Recalls are tied to your truck’s VIN, so check yours directly: enter the VIN at NHTSA’s recall lookup. Open safety recalls are repaired free at a dealer.
