1998 volvo s70 2.4 glt turbo


code p0102 refers to MAF/VAF sensor ---low input ===causes --wiring short to ground. MAF/VAF sensor
code po172 refers to system too rich --bank 1=== causes ---intake blocked --EVAP canister purge valve---fuel pressure ---HO2S sensor
code po random misfires ---plugs --wiring ---injectors--low compression
code po305 refers to cylinder 5 misfire detected ===causes --engine mechanical fault--ignition/ fuel system ---injector ---ECT/MAF

I would check that the air filter is not blocked first as it affects the MAF/VAF sensors . Have a fuel pressure system pressure test done

My car is chevy impala ls 3.82002 ,she have code 420,102,128


Use Google
Type----OBD PO420
Then OBD PO102 etc
Add your vehicle if you need more info
The 420 is a failed exhaust converter
Better find out why & fix that before replacing it

2002 acura rxa po172 code


You can order the O2 Sensors closest to the engine
& install yourself

The downstream sensor at the converter outlet
should be okey,just do the upstream ones
every 100,000 miles or when they fail as yours has

Rock Auto.Com has the best prices & brand names

NTK,Bosch,etc
