What does this fault code mean?

This code means the voltage from the front oxygen sensor (bank 1, sensor 1) is too low while driving. It can be caused by the signal or ground cable being short-circuited to ground, or by a damaged front oxygen sensor.

Possible causes

Short-circuit to ground in the signal cable
Short-circuit to ground in the ground lead
Damaged front heated oxygen sensor (HO2S)

What you can do

1Read the fault code status with the ignition on and check whether the fault is active. Then clear the code and road test the vehicle
2With the connector unplugged at the oxygen sensor, use a multimeter to check that the signal and ground cables are not short-circuited to ground
3Check the connectors at the oxygen sensor for contact resistance and oxidation
4If the fault remains after the wiring has been checked, have a workshop try a new oxygen sensor

Symptoms you may notice1

The Check engine light comes on or behaves abnormally

What the fault can affect2

Front oxygen sensor control is switched off
Catalyst diagnostics are switched off
