Turbocharger Boost Sensor A Circuit

38 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

Dirty or faulty mass air flow sensor
Vacuum or intake air leak
Weak fuel pump or clogged fuel filter
Faulty fuel injector
Faulty oxygen sensor
Wiring or connector fault
