Lambda sensor characteristic (Bosch LSH 6)

[Robert]

Hi Guy,

Do you know the voltage characteristic of a Lambda sensor (LSH6 with eater from Bosch) ?
I've two sources and the figures differ quite a lot. Is the Volt1 or Volt2 the correct one ?

Lamda: 1.09 | 1.05 | 1.02 | 1.00| 0.99 | 0.98 | 0.97 | 0.90 | 0.85
eq AFR:16.02 |15.44| 14.99| 14.7|14.55 |14.41|14.26|13.23|12.5
Volt1(V): 0.2 | 0.3 | 0.4 | 0.5| 0.6 | 0.7 | 0.8 | 0.9 | 1.0
Volt2(V): 0.02| 0.06 | 0.07 | 0.12| 0.18 | 0.50 | 0.62 | 0.80 | 0.84

Thank you. Best regards,

Robert

I don't know. However Volt 1 looks too perfect, like it has been made up. Volt 2 looks far more like an O2 sensor, its almost a switch and that's all you really need to know.

Hi,

This is what I found on the web and in DTA ECU software. But I'm not totaly satisfied. The figures in red are 'extrapolation' in order to trace a 'logical' curve.
