How to fix my volvo p2179 code
code p 2179 refers to system too lean off idle bank2===causes ---fuel pressure --injectors ---intake leak
also refers to adaptive heated oxygen sensor (HO2S) control--bank 2---signal high===causes ---wiring ---short to positive --HO2S --ECM
at this point I would be focusing the attention on the HO2S sensor and it's wiring
the HO2S reports on the exhaust gas composition to the ECM so that fuel /air settings can be adjusted to maintain the gas composition within set parameters
if those parameters cannot be maintained then the ECM goes a bit funny in trying to adjust injector fuel settings , fuel pressure regulator settings ( if electronic controlled ) and MAF settings

I assume you meant to say fouling up??If so read on.
HelloThe engine
and automatic transmission in this vehicles drive train
are fully electronically controlled by a computer called the PCM
(Power Train Control Module). Whenever a problem like this occurs the
computer stores a record of the problem (there are of course some
exceptions to this, like the fuel pump, engine coolant temperature
sensor and MAF sensor for instance) in the form of a fault code in
its memory, to read these fault codes you must have the systems
memory scanned with a special tool. Once the fault code(s) are read
you then must perform the appropriate diagnostic testing to find and
resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A
TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPEDING YOUR
HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
