Abstract

A mass airflow sensor according to the present disclosure includes a housing, a sensor element, and a flow deflector. The housing defines an airflow passage configured to receive air flowing in a first direction. The sensor element is disposed in the airflow passage and generates a signal indicating a mass flow rate of air flowing through the airflow passage. The flow deflector is disposed in the airflow passage downstream of the sensor element, extends from an inner wall surface of the airflow passage, and is configured to inhibit air flow through the airflow passage in a second direction that is opposite of the first direction.
