I have a 1993 ford taurus 3.8L V6 automatic GL. I retrieved these codes from my car: Code 157- mass air flow sensor fault, low voltage. Code 172- HEGO (HO2S) sensor fault/lean. Code452- vehicle speed sensor signal fault. Can you tell me what this means and what is wrong with my car?
Do you
have the same problem?

I got them from a "Innova ford digital OBD 1 code reader." I did a "KOEO" self test. They came from the code reader's memory.
