An O-ring test apparatus for a mass air flow sensor having a lift mechanism for lifting the mass air flow sensor and its production line carrier from the production line to a test location. In the test location, a clamping mechanism clamps the mass air flow sensor to the carrier compressing the O-ring. A seal mechanism blocks one end of an air flow passage provided in the production line carrier and connects an air inlet member to the other end. The air inlet member is connected by a manifold to a source of pressurized air through a solenoid valve. A pressure sensor connected to the manifold generates at least a first pressure signal in the manifold which rises to a pressure indicating that the O-ring is properly mounted on the mass air flow sensor. A control circuit activates the lift mechanism, the seal mechanism and the solenoid valve in a predetermined sequence and generates a fail signal in the absence of the first pressure signal when the solenoid value is open.
