CautionSeverity: Caution - get it checked when you can
O2 Sensor Circuit Slow Response (Bank 1 Sensor 1)
Key terms: Catalytic converter: cleans the exhaust gases · Oxygen sensor: measures oxygen in the exhaust gas · Bank 1: the side of the engine containing cylinder 1 · SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions
1What it means in plain English
The oxygen sensor before the catalytic converter is responding slowly to changes in the exhaust, which usually means the sensor is ageing.
2Common causes
- Ageing oxygen sensor
- Exhaust leak before the sensor
- Contamination from oil or coolant
- Vacuum or intake leak
- Damaged wiring or connector
3Can I drive?
Usually safe to drive. Fuel economy and emissions may be affected; have it checked before an inspection.
