Code p0171 refers to system too lean, bank 1 causes---intake /exhaust leak---AIR system---MAF/VAF sensor---fuel pump pressure/pump---injectors---HO2S (Oxygen sensor)
Replace the faulty units with genuine one because most
aftermarket units are not set for OEM cpu units and are not completely compatible.
