Best Automotive Replacement Mass Air Flow Sensor Relays in 2022

Last update: December 17, 2022

Can I use isopropyl alcohol to clean MAF sensor?

Yes, you can use isopropyl alcohol to clean your MAF sensor. Just be sure to disconnect the sensor from the car before doing so. Spray a small amount of alcohol onto a cloth and wipe the sensor until it is clean. Reconnect the sensor and start the car to check that it is working properly.

Can you clean a mass air flow sensor instead of replacing it?

A mass air flow sensor measures the amount of air entering the engine. The sensor is located between the air filter and the engine, and it is usually a round, black disc. Over time, the sensor can become clogged with dirt and debris, which can cause the engine to run erratically. If the sensor is clogged, you can clean it with a Mass Air Flow Sensor Cleaner. This is a aerosolized aerosolized aerosolized aerosolized aerosolized aerosolized aerosolized aerosolized cleaner that is sprayed into the air intake of the engine

Can you run a car without a mass air flow sensor?

A mass air flow (MAF) sensor is used to determine the amount of air flowing into the engine. This information is used by the engine control unit (ECU) to calculate the appropriate amount of fuel to inject. Without a MAF sensor, the ECU would not know how much air is entering the engine and would not be able to properly calculate the amount of fuel to inject. This would result in an excessively rich or lean air-fuel mixture, which would lead to engine damage.

Do you have to reset after changing MAF sensor?

No, you don't have to reset after changing MAF sensor.


Hitachi MAF0047 Mass Air Flow Sensor Review:


After tinkering with a P0171 code and once getting a P0132 (low voltage to MAF sensor), I bought this part for my Buick Regal LSE 2001 because I was experiencing sputtering during acceleration and erratically shutting off the engine. I took good care of my 148k-mile automobile, but these issues bothered me. I identified an intake leak "after the MAF sensor," changed the "bank 1" sensor, and still experienced sporadic "chugging" and sputtering. The fuel filter replacement was long overdue, and it was dirty (lesson learned). Since my "throttle body" was also produced by Hitachi, I was going to purchase the "Delco," but after reading reviews about this sensor made in Japan, I decided against it because THIS IS THE CORRECT PART for this application. It arrived PROMPTLY and was installed in a timely manner (2 screws and re-connect the "plug in" ) For the "security torx" fittings you will need (at least for the Buick), "Harbor Freight" is your buddy. The fix was simple, and as of yesterday, the chugging, burping, and stalling have stopped. Instead, now when I press the accelerator for the light, the acceleration is BALL* TO THE WALL. Excellent product and service from Amazon. thanks



Hitachi MAF0033 Emission Sensors/Valves Review:


I was right. You can't beat this sensor; just because Honda used it as the original doesn't make it bad; it's called a fluke! If you're buying this for your Honda or Acura and you got a bad one or it's failing, check the live scan tool data. If it's spiking at idle...or just a rare failure...this is the problem and solution. This is top-notch material! same, flawless form and function! (First, check for vacuum leaks!!!) You can be sure it will reach you safely because it comes in a box six times its compact size and is element protected and bubble wrapped. A great product at a discounted price arrives at your door quickly thanks to Amazon. You guys are hitting 1.000!



Walker Products 245-2198 Mass Air Flow Sensor Review:


Product of excellent quality and reasonable cost. After installation and a 15-minute test drive on a local street and the freeway, it precisely controls air flow in the low, mid, and high ranges. The engine power also returned, allowing for a smooth acceleration. You get the desired performance, just like a new automobile. installed on my 235,000-mile 2003 Ford Expedition, a baby. STRONGLY RECOMMENDED.

The item was of excellent quality and was a perfect fit for my 2000 E46 323ci. Before reviewing it, I took my time to make sure everything was in working order.My previous sensor problem was fixed by the product, and everything has gone a lot more smoothly overall. But just a heads-up. Just be patient after replacing the sensor as it will take some time for the car to readjust the fuel trims back to normal. "It took me almost a week of daily commuting before I started to notice better fuel efficiency and smoother driving," said one person who had a failed sensor and waited "2 months or so" before getting this replacement.I appreciate your excellent goods.



Hitachi MAF0012 Mass Air Flow Sensor Review:


SEL 2.5L 4-cylinder 2010 Ford FusionMy car began to feel like the transmission was slipping gears at 99,800 miles. I had to bring it in to have everything covered by my 100,000 mile warranty. To cut a long tale short, they cleaned the MAF after claiming it was unclean. Great, the issue has been resolved. At 103,000 miles, the issue reappeared. I cleaned it with some MAF cleaner spray, reinstalled it, and cleaned it. Up until 104,500 miles, it persisted. The original MAF was flawed, to put it simply. I double-checked the air filter's cleanliness and replaced it just to be safe.I was a little skeptical after reading and seeing reviews where the numbers were removed. An MAF, however, was available at nearby auto parts shops for $125–$200. This was available for same-day delivery on Amazon. It comes after I order it, at 7:30 PM (typical delivery time for my house on same day). I install it the next morning, and the vehicle has been functioning flawlessly.Tips/Hints for Do-It-Yourselfers1. Verify which way the flow arrow points before removing the old MAF.2. Take a moment more to make sure you don't lose a screw. I had to search for and retrieve the dropped screw for 15 minutes.Without the missing screw, the installation took two minutes.Required skill level: Can you plug in a toaster?

MOSTPLUS High Performance Mass Air Flow Sensor MAF for Chevrolet Buick GMC V6 Engine only 25180303 Review:


So, the check engine light appeared suddenly on my 2001 Impala 3.4. When I went to have it read, it gave me the code P0102 for the MAF sensor. I cleaned the old one, but the code persisted. So I took a chance and ordered this one after seeing that it was significantly less expensive but that the others had been successful. I put it in, changed my code, and drove it. After a few days, everything was fine until the code turned back on.Consequently, I'm thinking to myself, "Great, I'm a sucker for assuming an aftermarket part was going to work; even my mechanic friends warned me against doing that. I so pretended it was a loss and prepared to try returning it. Despite the fact that it was making my car act strangely, I inserted the previous one again and resolved the code issue.However, after watching a video on how to test a MAF to determine if it was effective or not, I decided to try an experiment anyhow. I connected the plug to the old one and checked the connectors' electrical voltage. The previous one didn't register and failed. So I gave this new one a try, and surprise, surprise, it registered perfectly well. I then go through the process once more to rule out any possibility of human error. But regrettably, I got the same exact outcomes. I also discovered that it takes the car up to 100 miles to accept new sensor data. So I reinstalled the new one, and naturally after two days the code reappears. But I forced myself to just give it a week; I could have driven the 100 miles with no problem.To my astonishment, the engine light was gone and the car was driving smoothly when I turned it on around 50 miles later. I haven't had any problems with it at all for a little over three months. Do yourself a favor and use this MAF if you need one. Just allow the car some time to lock in the new settings, and you will be OK.



MOSTPLUS MAF Mass Air Flow Meter Sensor AFH50M-05 3 Pins for Buick Chevrolet Oldsmobile Pontiac 213-3428 Review:


Installed on a 2002 Buick Lesabre with no problems after roughly 1000 miles. I purchased this in an effort to solve a vehicle issue because I believed there was a potential the mass sensor would be the culprit. In the end, it wasn't. I still have it installed and my previous one as a backup even after the issue was resolved. I won't be surprised if it doesn't travel a great distance, and I doubt I'd change my ranking even then. I was able to get a functional sensor for less than $20 that would have cost at least $80 for a solid aftermarket sensor or maybe $200 for one from a stealership. It was a reasonable guess that prevented me from repairing the genuine issue by climbing beneath the car in the middle of the chilly garage.Edit 10/30/19. This device is still functioning properly after about 10,000 kilometers. Car is running flawlessly. fantastic purchase for the money.



Walker Products 245-1108 Mass Air Flow Sensor Review:


With ALL the trimmings, my fuel system was giving me trouble! The CVPI is a GREAT Car, but due to its past life as a police interceptor and the additional duties and equipment that go with with it, EVERYTHING IN THE ENGINE COMPARTMENT IS BASICALLY WIRED INTO EVERYTHING ELSE! It was difficult to say the least to figure out which code I was getting because I was getting ones for broken sensors, connectors, and fuel—especially since I am not a mechanic, but a stereo guy instead! Needless to say, after repairing the connector, adjusting the sensor, and adding some Sea Foam Fuel System Cleaner, my baby once again RUNS LIKE A SCALDED DOG! The connector issue was resolved when I had to swap it out for a secondhand one from a friend's junk yard.



Hitachi MAF0031 Emission Sensors/Valves Review:


In general, OEM items work best. The mass air flow sensor is a case in point. It works wonderfully and resolved my stalling/stuttering problem. For Nissan vehicles, be sure to follow the instructions for relearning the intake air volume. If you don't, the replacement sensor might not make a difference until you do.

Thank you for letting me return it; the second item was excellent for the car.


Do you have to unplug battery when replacing mass air flow sensor?

Replacing a mass air flow sensor is a pretty easy job that can be completed in about an hour. The most important thing to remember when replacing this sensor is to unplug the battery before starting. This will ensure that you don't accidentally short circuit anything while working.

Does a MAF sensor need to be calibrated?

A MAF sensor measures the amount of air flow entering the engine. Over time, the sensor can become dirty or damaged, which can cause it to give inaccurate readings. In some cases, the sensor may need to be recalibrated to ensure accurate readings.

Does a new map sensor need to be programmed?

If you're replacing your map sensor, you'll need to reprogram it. Most map sensors come with a sticker that has the programming information. If you don't have that, you can usually find the programming information online.

Does MAF have a fuse?

The short answer is no, the MAF sensor does not have a fuse. The MAF sensor is powered by the battery and sends a signal to the engine control unit (ECU). The ECU uses this signal to adjust the air/fuel mixture that is delivered to the engine. If the MAF sensor is not working, it will often cause the engine to run lean (too much air and not enough fuel).

How do I factory reset my MAF?

To factory reset your MAF, follow these steps: 1. Press and hold the MAF button for 3 seconds. 2. The MAF will beep and the display will show "FACTORY RESET" 3. Press the MAF button again to confirm. 4. The MAF will reset and the display will show "MAF RESET"

How do I reset my car after replacing the MAF sensor?

If you have replaced your car's MAF sensor, you will need to reset the car's computer. To do this, disconnect the negative battery cable for 30 seconds. This will reset the computer and clear any codes.
