What is the mass air flow sensor on a Subaru Outback?
2001 Subaru Outback 2.5L 5 Speed Manual. The Mass Air Flow (MAF) Sensor measures the flowrate of air through the air intake before reaching the engine. Since the density of air changes with temperature and pressure (due to ambient temperature, altitude), the ECU needs this information to provide the correct fuel mass to the engine.
How much does it cost to replace a Subaru air flow sensor?
But if it reads no resistance a maf code is the likely outcome. Use a volt meter to check if the wiring is faulty. A Subaru Outback is misfiring and the local garage says the mass air flow sensor has to be replaced which will cost $447 without labor.
How to clean the MAF sensor in a Subaru?
Disconnect the wiring harness, remove the two screws and carefully pull the MAF Sensor from the housing. Then, spray the MAF Sensor with the CRC. The hot wire (circled in blue below) is the important part you need to clean, but I usually just douse the entire piece with CRC to remove all particulates.
Why is my mass air flow sensor not working?
On starting a Subaru Impreza where the mass air flow sensor was changed the oil temperature light flashes and the engine sends a maf code what could the cause be? If after replacing the mass air flow sensor the code still remains, chances are that the issue is with the wiring to the sensor rather than with the sensor itself.
What is the air flow sensor on a Subaru Legacy?
With its driving comfort and easy handling, your Subaru Legacy makes each trip about the destination by easing your journey and letting you relax while you drive. Keep that balance by replacing the Subaru Legacy MAF sensor whenever yours malfunctions, so that your engine always responds with the horsepower you expect.
When to replace the Subaru Legacy MAF sensor?
Keep that balance by replacing the Subaru Legacy MAF sensor whenever yours malfunctions, so that your engine always responds with the horsepower you expect. AutoZone is your one-stop shop when you’re in need of high-quality replacement parts.
What does the legacy mass flow sensor do?
The Legacy mass flow sensor measures the amount of air coming into the engine. This information is then used by the engine control unit (ECU) as part of its calculations for the optimum fuel ratio, allowing your engine to flex with the conditions and your driving style, delivering a consistent performance.
Why does the ECM on my Subaru not work?
Same with the ECM. And if the electrical flow is low, solenoids and switches will either work poorly or not at all. Start with the battery and check ampere output and work outward from it. Corrosion is resistance. loose pins at the plugs mean sporadic outputs or operation. Check them.
