What is Wideband lambda?
What is Wideband lambda? A wideband sensor calculates lambda by comparing the oxygen left in the exhaust to the sensor's reference pump cell, which is referencing stoich. Because the sensor reads oxygen content, it is impartial to the fuel type being used. What does a Wideband measure? Wideband/Air-Fuel sensors perform the same function as a regular O2 sensor, but they precisely measure the amount oxygen in the exhaust rather than just switching between rich (too much fuel, not enough oxygen) and lean (too much oxygen, not enough fuel). How many ohms should an oxygen sensor read? CHECKING THE LAMBDA OXYGEN...
