S80 T6 - Engine codes please help explain how to fix

Post by Honeyb87 »

P1174-Fuel System 1 and 2 Closed Loop
P0153-Curciut Slow Response Bank 2 Sensor 1
P0172-System Bank Too Rich Bank 1
P0175-System Bank Too Rich Bank 2

I am hoping one of these is making the other codes go off. Please help me figure out what these mean.

Thank you!!

Welcome to Matthew's Volvo Site.

They all have one thing in common, a faulty heated oxygen sensor (HO2S).

P0153 is a faulty front HO2S which is, in all probability, triggering the others.
