I have a 2014 Mazda 3 hatchback with 180,000 miles on it. The car has been a great car but I just had the check engine light, traction control light, and tire pressure light come on. The code reader gave me half a page of codes and recommended changing the mass airflow sensor, which I will start with. My question is if it turns out to be the TCM, where is that located on the 2.0L engine? I have been searching and cannot find any information on it. Much thanks.
