Severity: Caution - get it checked when you can

Downstream oxygen sensor signal failure

30 brands affected · Description from Toyota data.

Key terms: Oxygen sensor: measures oxygen in the exhaust gas · Control module: a small computer that runs one part of the car · Powertrain: engine, transmission and emissions

1What it means in plain English

The engine or powertrain control system has stored a fault that does not have specific guidance in this database yet.

2Common causes

Sensor or actuator fault
Wiring or connector fault
Vacuum or intake leak
Fuel or ignition problem
Control module fault

3Can I drive?

Caution · drive with care

Have it diagnosed promptly. If the car runs and drives normally, drive gently to a workshop. If it runs badly, stalls, overheats, loses oil pressure, or a warning light is flashing or red, stop safely and get professional help. If the code concerns the brakes, brake vacuum or brake assist, do not drive until it is checked: a hard pedal or longer stopping distance means stop.

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.
