Boost pressure sensor signal error
Key terms: 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 · 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
3Can I drive?
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.
