How does the air mass sensor work in a diesel engine?
The air mass sensor precisely measures the air mass that flows into the engine (“mass air flow”). The signal from the air mass sensor is used to calculate the injected fuel quantity. In diesel engines, it also controls the exhaust gas recirculation. It is an important component in air supply and helps reduce exhaust gas.
What can cause a MAF sensor to fail?
The sensor element could get contaminated or damaged. Sometimes, an improperly-installed or ripped air filter can cause the MAF sensor to fail sooner. Over-soaking a washable air filter with oil can also cause troubles with the air flow sensor.

All of it depends on circuit that’s being built. According to previous, the lines at a Mass Air Flow Sensor Wiring Diagram represents wires. At times, the cables will cross. But, it doesn’t mean connection between the cables. Injunction of two wires is usually indicated by black dot in the intersection of 2 lines.
The Mass Air Flow Sensor measures the amount of air volume flowing into a car’s engine, and sends the Electronic Control Unit (ECU) a voltage that represents the airflow. Currently the most common MAF sensor is the plug-in hot wire type which is located inside the intake air duct between the air filter and the throttle body.
How much does it cost to replace a MAF sensor?
MAF Sensor Replacement Cost. A Mass Air Flow Sensor is not so cheap but it is not very expensive either. You could get one for $120 – $300 to which you should add labor costs of $80 – $100. Therefore, on average you are expected to pay $200 to $400 in total for a mass air flow sensor replacement.
Can a bad mass air flow sensor trigger a check engine light?
Bad mass air flow sensor with no check engine light? Sometimes a mass airflow sensor can start to fail and even trigger engine error codes such as P0101 and P0102, without triggering a check engine light. There must be a problem with the mass airflow sensor circuit for the check engine light to illuminate.
Where is the mass airflow sensor in a car?
To begin testing, the first thing to do is to locate it in the car. Open the car hood and you can find it just between the throttle body and air filter. It is inside the filter house in some car models. However, it is expected to be mounted around the air duct area.
Bad mass air flow sensor with no check engine light? Sometimes a mass airflow sensor can start to fail and even trigger engine error codes such as P0101 and P0102, without triggering a check engine light. There must be a problem with the mass airflow sensor circuit for the check engine light to illuminate.

What does the MAF sensor tell the ECU?
In the majority of factory cars a MAF sensor is used to tell the ECU what mass of air is entering the engine. In stock form the calibration of this sensor is likely to be close to perfect, however as soon as we make any changes to the intake system the MAF calibration can become inaccurate.
The sensor, located between the air filter and the intake manifold, contains a hot wire and a temperature sensor. The hot wire is heated with an electrical current. As your vehicle accelerates, the throttle opens, allowing the air that enters the engine to pass through the MAF.
Which is the best AutoZone air flow sensor?
AutoZone carries hundreds of thousands of parts and accessories. Select your Year, Make, Model and Engine to find those that fit your vehicle. Put a stop to engine hiccups and stabilize your engine’s air-fuel mixture with a new mass air flow sensor (MAF) from AutoZone. We carry great brands like ACDelco, Bosch, Duralast, Hitachi, and more.
What are the symptoms of a bad mass air flow sensor?
Symptoms of a bad mass air flow sensor include decreased fuel economy, starting trouble, stalling shortly after starting, rough idling, and jerking during acceleration. If your check engine light is on and your car has any of these symptoms, you can check the MAF sensor with an OBD-II code reader.
How does a MAF sensor work in a car?
Analog MAF sensors produce a variable voltage output, whereas digital sensors send a frequency output. Both outputs are sent to the engine control module to regulate air-fuel mixture and the automatic transmission system. Regardless of the type of MAF, the sensors work similarly.
We recommend Parts Geek or Advance Auto Parts for the best prices and selection. The mass air flow sensor is a fairly small part but not the cheapest to replace. The good news is that it’s usually located near the top of the engine and DIY replacement is easy in most cases.
What should I replace on my 1991 Saab 900?
