Benefits of Pressure Sensors for Measuring Airflow

+

Mass Airflow Sensors A mass airflow sensor is a device with two pressure ports where air/gas flows from the first port to the second. Inside, there’s a sensing element with a heated surface. As air or gas flows across the sense element, heat is transferred. This creates a thermal imbalance proportional to the flowing mass.

It does this because the Barometric Pressure Sensor is actually part of the Mass Air Flow Sensor. Sometimes the Air Flow Sensor and the sensing wire get covered with dirt, dust, or oil residue, which can set a P0171 in addition to the P0102 code. Cleaning the sensor might hold off problems for a while, but the MAF sensor should be replaced.
