Info

Severity: Info - usually nothing urgent

O2 Sensor Heater Circuit (Bank 1 Sensor 1)

42 brands affected · Generic SAE J2012 description.

Key terms: Catalytic converter: cleans the exhaust gases · Oxygen sensor: measures oxygen in the exhaust gas · Control module: a small computer that runs one part of the car · 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 heater inside the oxygen sensor before the catalytic converter is not working, so the sensor takes longer to warm up and start controlling the mixture.

2Common causes

  1. Faulty oxygen sensor heater
  2. Blown fuse
  3. Damaged wiring or connector
  4. Corroded connector
  5. Engine control module fault

3Can I drive?

Info · normally safe to drive

Usually safe to drive. Emissions and fuel economy may be slightly worse until it is fixed.

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.
