Measures the air flow for the secondary air injection system

Mass air flow sensors are tasked with measuring the amount of air entering the engine via the intake. This mass air flow sensor is known as a hot film sensor which will suffer performance deterioration over time. The sensor is designed to be self cleaning. A faulty or non functioning mass air flow sensor will cause a check engine light and in some cases cause a limp mode. The best way to diagnose a faulty mass air flow sensor is to disconnect it and see if engine idle or performance improves.

Fix For Common P0411 Secondary Air Injection Incorrect Flow Detected

Replaced this part after getting a check engine light on cold start ups that would not go away. The downloaded fault code was P0411 - Secondary Air Injection Incorrect Flow Detected. Diagnosed the secondary air system and found the air pump, hoses, and check valve to be in working order. This part was the last item in the system that could be causing the fault code. It is basically a mini mass air flow meter and when it fails, the DME cannot detect if air is flowing into the engine or not. Once this part arrived, I popped it in place in about 10 seconds, cleared the fault code, and perfection! No more fault code and my secondary air injection system is back in working order!
