Most Reported On
P132B is an OBD-II diagnostic trouble code meaning “Turbocharger/Supercharger Boost Control 'A' Performance Problem (manufacturer-specific).” P132B is a manufacturer-specific powertrain code, defined by Ford and similar makers as a Turbocharger/Supercharger Boost Control 'A' Performance Problem. The PCM commands a boost level via the boost control system (wastegate, solenoid, or vane actuator) and detected that actual boost did not match the commanded value. This usually means the engine is producing too little or too much boost, leading to reduced power, hesitation, or limp mode, and it should be diagnosed to avoid further driveability or turbo problems. This code is most commonly reported on 2011-2022 GMC Sierra 3500HD, 2007-2024 RAM 2500 (2500 6.7L Cummins), and 2003-2007 Ford F-350, with repair costs ranging from $200 to $3,500.
