Textbook Problem

While discussing zirconium O2S diagnosis: Technician A says that the voltage signal on a satisfactory O2S should always be cycling between 0.5 voltand 1 volt. Technician B says that a contaminated O,S may produce a continually high voltage signal. Who is correct?

  1. Technician A

  • Technician B
  • Both A and B
  • Neither A nor B
  • To determine

    The technician with correct approach.

    Explanation

    Given information:

    Technician A says that the voltage signal on a satisfactory O2S should always be cycling between 0.5 volt and 1 volt.

    Technician B says that a contaminated O2S may produce a continually high voltage signal.

    Oxygen sensor is installed in the exhaust pipe in automobiles. It helps in producing a voltage which depends on the temperature and the concentration of the oxygen in the exhaust. This sensor can generate a voltage signal inside the exhaust gas pipe.

    Zirconium sensor consists of an element of zirconium, a plate of platinum, and a heater. The zirconium element is exposed to atmosphere from the side and the other side faces the exhaust gas pipe. The side facing atmosphere is connected to the wires of the sensor...
