Lambda / Oxygen sensor voltages 3.0 24V CF3
I'm, lucky enough to have a CF3 engine with 4 lambda's, and want to bottom out if my lack of power is due to one of them. I have connected a diagnostics tool to them with the engine running and found the following:
Bank 1 sensor 1 - 0.445V all the time, no matter what the RPM
Bank 2 sensor 1 - 0.445V all the time, no matter what the RPM
Bank 1 sensor 2 - adjusts according to RPM (0.1-0.7V), oscillating voltage on idle
Bank 2 sensor 2 - adjusts according to RPM (0.1-0.7V), oscillating voltage on idle
Does that mean that both sensor 1's are not doing anything, i.e. given up or just not warming up? Or should they be static across the rev range (which doesn't sound logical to me with increasing revs and higher fuel burn)? Sensor 1's are on the manifolds as well?
Any help appreciated!
