Hyundai Santa Fe bad mass air flow sensor (MAF) symptoms and causes

The mass air flow sensor or MAF sensor is part of the intake system in Hyundai Santa Fe responsible for measuring the amount of air entering the engine. Driving your Santa Fe with a bad MAF sensor can damage the engine, so you must act urgently to avoid more expensive repairs.

The most common signs of bad mass air flow sensor (MAF) in Hyundai Santa Fe are loss of power or slow acceleration, engine hesitation or jerking during acceleration, erratic idling, misfires, poor exhaust emission values and sometimes black smoke comes out of the tailpipe.

The mass air flow sensor is part of the engine’s intake system and is located between the air filter and the throttle body. It is not only important for power delivery in your Santa Fe, but also for the lowest possible pollutant emissions.

What happens when MAF sensor malfunctions in Hyundai Santa Fe?

If the MAF sensor is defective or dirty, it does not send correct measured values ​​to the control unit of Santa Fe. The optimal amount of fuel can no longer be calculated which results in either too little or too much fuel injected into the combustion chambers. The engine runs too “lean” or too “rich”. This can cause the engine warning light to illuminate in the instrument cluster and the fault can be read out by a diagnostic device.

What causes MAF sensor to fail in Santa Fe?

Dirt accumulation

The most common cause of a malfunctioning MAF sensor in Hyundai Santa Fe is dirt and grime accumulation on the sensor. Air filters are effective at cleaning the air to a certain extent. When the vehicle is running, dirt and other airborne particles that escape from the air filter can settle on the sensor. And over time when enough dust accumulates, the sensor starts to give erroneous readings.

Too many miles on the sensor

The mass air flow sensor is a wearing part. As the mileage increases on your Santa Fe, it can happen that increasingly inaccurate values ​​are sent to the engine control unit. With a noticeable loss of performance and high mileage, a defective MAF sensor should definitely be considered. There is no fixed timeline for when MAF sensors fail, sometimes they can last the lifetime of the vehicle, other times than can fail even before the warranty expires.

Water damage

When driving fast in heavy rain, water can occasionally pass through the air filter and can damage or contaminate the MAF sensor, which can severely impair its functionality.

Oil damage

In rare cases, the MAF sensor can also be damaged by oil vapors flowing back out of the crankcase ventilation after the engine has been switched off.

Bad connector or electrical wires

In rare cases, it is possible that the fault codes or the symptoms you’re seeing in your Santa Fe are not due to a bad MAF sensor, but because of broken electrical wires or a bad connector. This can especially happen in older vehicles or in case of rodent damage.

How to check if the MAF sensor is bad in Hyundai Santa Fe?

Reading out the fault codes using a diagnostic device is relatively reliable. If you see P0100, P0101, P0102, P0103 or P0104 code in the OBD2 scanner, it indicates a problem with the mass air flow sensor. However, it can happen that there are no error codes. In case of doubt, the sensor may have to be replaced. But this should only be done after an extensive analysis as the MAF sensor may not be responsible for the symptoms of poor acceleration in your Santa Fe.

A more accurate diagnosis can be performed by analyzing the MAF sensor Parameter Identification Data (PID) information on a scan tool. However, this should be best left to trained professional mechanics, as it requires reading and interpreting the measured values from the MAF sensor.

Cleaning dirty MAF sensor in Hyundai Santa Fe

Cleaning the mass air flow sensor can help the sensor measure the correct values ​​again, but only if the erroneous readings are caused by dirt accumulation. However, caution is advised here, as the sensor parts are very sensitive to touch.

1. Find the location of the MAF sensor in your Santa Fe, it will be somewhere between the air filter box and the throttle body.
2. Unplug the electrical connector.
3. Remove the sensor from the housing.
4. Spray at least 10 spurts of MAF cleaner onto the sensor and then let it air dry for an hour or until completely dry.
5. Put everything back together and start the engine.

Note: Do not use a cloth or cotton swabs to clean the sensor. Also, do not use anything other than the MAF cleaner to clean the sensor, otherwise the sensor may get damaged.

To begin troubleshooting, you must first connect the diagnostic tool to your Santa Fe. The OBDII connector is usually located under the dashboard. With the tool connected, turn on the ignition. Most diagnostic devices then ask for some information about the vehicle. It is important that you enter this 100% correctly, otherwise the result of the search may be inaccurate. In addition to the vehicle make, model, and engine type, you usually also have to type in the Vehicle Identification Number (VIN). Since some OBD codes are manufacturer-specific, the scanner will be able to give you more accurate information if you enter more details about your Santa Fe.

Diagnostic error codes for MAF sensor

P0100 = Mass or Volume Air Flow Circuit Malfunction
P0101 = Mass or Volume Air Flow Circuit Range/Performance Problem
P0102 = Mass or Volume Air Flow Circuit Low Input
P0103 = Mass or Volume Air Flow Circuit High Input
P0104 = Mass or Volume Air Flow Circuit Intermittent

Conclusion

There are many reasons why MAF sensor is malfunctioning in your Hyundai Santa Fe. When looking for the reason, you should always start with the most obvious cause, dirty MAF sensor that only needs cleaning.

In any case, it is advisable for laypersons to visit a workshop. A professional mechanic can swiftly diagnose the problem for you.

Hyundai Santa Fe: Bad MAF Sensor → Symptoms & Causes

The mass airflow sensor (commonly abbreviated to MAF) is one of the most important engine management sensors. A bad mass airflow sensor can leave your Hyundai Santa Fe’s engine running rough, or even inoperable.

A MAF sensor measures the density of the air entering the intake manifold. It passes this information onto your Santa Fe’s ECU. The ECU uses this information along with other sensor data to control the amount of fuel that enters the combustion chamber.

If you do determine that you need a new mass airflow sensor, they aren’t too expensive. And, most of the time they are right by the air box and easy to replace.

Faulty Mass Airflow Sensor Symptoms: Hyundai Santa Fe

When the mass airflow sensor has gone bad, you’ll definitely feel it. Here are the most common symptoms of a bad or failing MAF sensor:

• Idle Issues– Your Santa Fe may run rich or lean when idling, or it may also idle erratically. A rich condition is when there is not enough air relative to the fuel in the air/fuel mixture. The exhaust color is usually darker when running rich. A lean condition is when there is too much air relative to fuel in the air fuel mixture. The exhaust color usually doesn’t change.
• Hard to Start– Without knowing the proper amount of air entering into the intake, it can be really difficult for the engine to start. And when it does, it doesn’t usually run very well.
• Jerking– As you go down the road, you’ll feel your Santa Fe really jerk and hesitate as the engine speed changes erratically. It’s bad for your motor mounts when this happens. Also, jerking can be caused by bad spark plugs or coil packs.
• Decreased Fuel Mileage– Fuel mileage can suffer without the proper air/fuel mixture.

Santa Fe Bad MAF Sensor Diagnosis

If the MAF sensor has gone bad, it’ll trigger the check engine light and provide an OBDII trouble code. This is great because it helps you narrow down the problem. The two most common trouble codes in relation to the MAF sensor are:

There are other codes related to the mass air flow sensor as well, but these are the most common ones. Here’s a fantastic video on how to diagnose a bad MAF sensor using a multimeter from Ratchets and Wrenches on YouTube.

Cleaning the Mass Airflow Sensor

Often, the mass airflow sensor really only needs cleaning when they go bad. Some folks recommend using alcohol because it’s usually on hand, and can clean the sensor. This is a bad idea, it can ruin the sensor. Uses mass airflow sensor cleaner. It’s really cheap and available at any parts store. It sure beats the heck out of having to buy a new sensor.

1. Locate the MAF Sensor– It’ll be in between the air filter and the throttle body.
2. Remove the Sensor- Take care not to damage the wiring harness or the connector pins that receive the harness in the MAF. Simple hand tools will be all that you need to complete the job.
3. Clean the Sensor– Now that you’ve removed your Santa Fe’s MAF sensor, it’s time to clean it. You’ll need the MAF cleaner. You are not scrubbing anything. Let the chemicals do their job. About a dozen small bursts will be all that you need.
4. Replace the Sensor

Conclusion

Replacing a bad MAF sensor can make your Santa Fe feel like a new vehicle. Good luck with the diagnosis. If there is anything that you would like to add, please feel free to leave a comment below.
