I have a 56 plate Citroen c2 1.4 petrol with the mill light keeps coming on.
Codes
P0138 Downstream oxygen sensor signal problem
P0132 upstream oxygen sensor signal problem
P0130 Upstream oxygen sensor signal
Now the weird thing is this, I go in to diagnostics via model year ect and then in to live Data, Upstream and Downstream pids are showing 0 volts straight line as if they are not working at all.
If I go in to obd2 live data it shows both working fine. and no codes
I think i have a wiring problem, but why do they show something different ?.
