A faulty MAF sensor can also trigger other codes, such as those pertaining to an air/fuel ratio imbalance or an engine misfire.
What codes will a bad mass air flow sensor cause?
Trouble codes P0171 System Too Lean (Bank 1) and P0174 System Too Lean (Bank 2) are also often caused by a bad or contaminated mass air flow sensor.
Can you have a bad mass air flow sensor without a code?
Bad mass air flow sensor with no check engine light? Sometimes a mass airflow sensor can start to fail and even trigger engine error codes such as P0101 and P0102, without triggering a check engine light. There must be a problem with the mass airflow sensor circuit for the check engine light to illuminate.
