Turbocharger Boost Sensor A Circuit Range/Performance

36 brands affected · Generic SAE J2012 description.

Key terms: Turbocharger: an exhaust-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 powertrain range that covers fuel and air metering, over-temperature, overspeed and transmission over-temperature conditions.

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

Caution · drive with care

Do not assume this code is safe to ignore: some codes in this range affect engine safety systems. Have it diagnosed; if the engine is overheating, a red warning light is on, or the engine loses power or cuts out, 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.
