Final answer:
The wide-band oxygen sensor with a pump cell is called the Wideband Lambda Sensor or Wideband Oxygen Sensor and it uses a pump cell to control the oxygen concentration in the exhaust gas.
Step-by-step explanation:
The wide-band oxygen sensor that incorporates a pump cell is known as the Wideband Lambda Sensor or the Wideband Oxygen Sensor. This type of sensor uses a pump cell to actively control the oxygen concentration in the exhaust gas.
It operates by pumping oxygen across a porous electrolyte, which generates an electric current proportional to the oxygen concentration. This current is then used by the sensor to accurately determine the air-fuel ratio in the engine.
