My K11,1.4,2000 has two 4 wire oxygen sensors.I thought the second one should be after catalytic converter but as far as I can see it is underneath the engine on the same exhaust pipe as the first one(about 20"-30" distance) and no catalytic between them.What is the second one for then?
Both sensors seem externally same,just the cables length is different.Is this the only difference or signals are different?Usually signal of oxygen sensor when is single is between 0.1-0.9V.What about second one?
I know both sensors have different part numbers?What is the difference anyway?
