Question

2012 Toyota Camry V6 with engine codes P0101 and P0171, what do the codes mean?

Answer 1

Hi there,

The P0171 code can be caused by the mass air flow sensor which is the P0101 code you are showing. This points to the car most likely needing a new maf sensor. Also, check the air filter. Sometimes a dirty air filter will cause both codes.
