Alfa 147 2.0 Selespeed - Motor Control System Failure
Well, I have the above code on my car. It still drives absolutely fine (seemingly) and has recently had a new battery and MAF sensor.
The codes it brought up were:
P1177 Mixture adaptation multiplicative bank 1 not in range
P1178 Mixture adaptation multiplicative bank 2 not in range
P0725 Engine speed signal not plausible
From what I have found online it would seem this could be Lambda sensors or possibly injectors?
Can anyone shed any light at all? As I said, it seems to drive fine and since the new MAF sensor was fitted pulls wonderfully and revs right round happily.
Time to buy a new summer album!

and many thanks to you all
