Fault Code PO171

[VY SS UTE 777]

Hi Guys,

Have an active Fault Code PO171 and historic PO174 & 171

VY SS ute 190,000km

Stock unit no alterations

Starts and idles fine, temp at 50% when fault code is active (after around 5 mins driving) faults around once a week

Fuel Consumption 360km / tank 70lts, gentle around town driving.

Air filter and intake hose and AFM all look visually fine inside and out.

Any suggestions on what the issue is?

Hi.
Haven't a clue mate.

But this is what my Ellery workshop manual got to say about errors P0171 & P0174.

Hope it helps!
