Question about 1998 Saturn SW
P0171 (fault Location) System to lean, bank 1 (probable Cause) Intake/exhaust leak, AIR system, MAF/VAF sensor, fuel pressure/pump, injector(s), HO2S
HO2S is Oxygen sensor. MAF is Mass air flow sensor. Any one of these could cause a problem. Is this what your code reader said or does your code reader only read the codes and tells you nothing else?
