Heated oxygen sensor
"The oxygen sensor does not start to function until the working temperature exceeds 600°C (1120°F) and is therefore fitted with electrical preheating." This should read: "Since the operating range of the oxygen sensor is between 200 and 850°C (392 and 1562°F), it is equipped with electric preheating."
The illustration shows the oxygen sensor in the wrong position. It should be in front of the catalytic converter.
