What does this fault code mean?

The engine control module (ECM) monitors the rear oxygen sensor in bank 1 by checking its signal. The code is set if the signal deviates from its permitted range, or if the sensor's pre-heating voltage disturbs the signal. The fault is only interpreted once the limit values have not been reached after a certain time, and both the accumulated and the current preheating have reached their values.

Possible causes

Signal wire shorted to ground
Open circuit in the signal wire
Ground wire shorted to ground
Damaged rear oxygen sensor; on cars with three sensors the middle sensor may be the one concerned instead

What you can do

1Read the code, clear it and road test the car to see whether it comes back
2Use a multimeter to check that the signal wire from the sensor is not shorted to ground and has no open circuit
3Check the connectors at the sensor for contact resistance and oxidation; do not use rust solvent spray or grease
4If the connectors and wires are intact, replace the sensor

Symptoms you may notice1

Check engine light (MIL) on

What the fault can affect2

Control with the rear oxygen sensor is switched off
Catalytic converter diagnostics are disabled
