Turbocharger/Supercharger Boost Control A Circuit Low

36 brands affected · Generic SAE J2012 description.

Key terms: Turbocharger: an exhaust-driven fan that pushes extra air into the engine · Supercharger: an engine-driven fan that pushes extra air into the engine · Boost pressure: extra air pressure made by a turbo or supercharger · Oxygen sensor: measures oxygen in the exhaust gas · Mass air flow sensor: measures the air going into the engine · SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions

1What it means in plain English

This code is in the fuel and air metering range, which includes fuel-pressure and camshaft-timing faults.

2Common causes

  1. Dirty or faulty mass air flow sensor
  2. Vacuum or intake air leak
  3. Weak fuel pump or clogged fuel filter
  4. Faulty fuel injector
  5. Faulty oxygen sensor
  6. Wiring or connector fault

3Can I drive?

Caution · drive with care

Have it diagnosed promptly. Some codes in this range affect fuel pressure or camshaft timing; if the engine loses power, runs badly, or stalls, stop safely and get professional help.

This page gives general information. It is not professional advice. For a definite diagnosis and a repair quote, ask a qualified mechanic to inspect the car.
