Denso 197-6030 Mass Air Flow Sensor

Denso is the same brand that Toyota uses in its oem parts. I had two error codes, including the check engine light, and I purchased a very inexpensive replacement part, with no positive results. I also performed a complete cleaning of the connectors and the original MAF sensor, with no positive results. I installed the new Denso sensor, and as if by magic, all the error codes disappeared, and operation returned to normal. I've been testing for a few days, and so far, with over 200 km on the clock, there haven't been any problems. I recommend using a Denso sensor and not any other off-brand sensor.

Good stuff. I went with the Denso. I can’t attest to other MAF’s, but this did help keep idle RPMs more in check consistently.

One rainy day my Tacoma started up but shook like it was going to blow up or throw a rod. I was soooo bummed! Drove it to the shop 20 miles away. Two days later and $800 lighter, I got my Taco back. Mechanic said '3 hours of labor plus parts'. He replaced ONE coil, all the spark plugs, and the spark plug wires. I about popped a vein but that week was busy for me at my job so I didn't have time to do the work myself. So, I went on Amazon and bought three coils (yes, these are OEM Denso) and two sets of spark plug wires (OEM but priced at 60% less than the dealer). My Taco and my 4Runner (3rd Gen) have the same engines so the dealer had spark plugs at less than $3 each! Stocked up. Go on youtube and watch the 'how to change your spark plugs videos'. Super easy but make sure you have all the right extensions, nut drivers, sockets, and so on. Take. Your. Time. You do not want to mix up the wires. V6 3.7 L engines have THREE coils, not six and OEM coils easily last 200K miles and often go over 300k but if you're paranoid, change them the next time you change your plugs. It is NOT a three hour job but hey, all tradesmen seem to be pegged at $1000/day so if you want to save money, do it yourself. You need a torque wrench, a 'u-joint' adapter, metric sockets, extensions -- especially a 20-inch or so plus patience. Do it, you'll have a sense of satisfaction and accomplishment.

My little FIXD Bluetooth OBD2 scanner told me the check engine light was on because of a bad MAF sensor. I paid extra for this one because another review said it is OEM and I haven't replaced it before to the best of my knowledge. The one I just took out, which is indeed filthy on the one wire, is marked "Toyota" and "Denso" on the top. It's awfully simple to replace. There are two tiny screws and a cable to disengage. After installation, the FIXD let me reset the check engine light.After checking NAPA's outrageous price for the part and assuming a high charge for labor, I figure I might have saved $250-300 by doing it myself. I'm very happy.

EDIT: So frustrating that this part completely died in less than 2 weeks causing me to not be able to start my car successfully. It would start and then immediately die. I was in an area where I couldn't leave my car so I ended up having to pay for a tow, some diagnostics at a mechanic to confirm the MAF sensor was bad (I had a feeling it was the MAF but wanted to be sure), and then a new MAF sensor which I again replaced myself (mechanic wanted to charge over $300 to replace the MAF, but I was definitely not paying that since I knew that even at full price the part is around $100 and it takes literally a screwdriver and 2 minutes to replace).All in all, this part was a $300 mistake. I was correct in replacing the part, which solved my issue and saved me a lot of money (>$300 for a mechanic to do it, compared to just the price of the part), but because I got a crappy part all that savings went down the drain. Live and learn. I suspect the part I received was either not genuine Denso (my OEM Denso MAF lasted almost 20 years!), or was used. Very disappointed and now wary of buying products like this from Amzn in the future since they can be dubious in origin or quality.Original Review Below:2002 Camry V6, ~130k miles. I got the dreaded check engine light and really didn't want to spend money on such an old, beat up, car. I enjoy DIY fixing a lot of home stuff, but I am an idiot when it comes to cars. Found some easy trouble shooting tips like changing the air filter and cleaning the MAF sensor. Cleaning the MAF cleared the code for a few months but then it came back.Continued to drive it around for a couple months, thinking that it would be expensive to fix, and my car was definitely not driving very smooth. Do not do this as it's really not good for the engine! Then I finally realized that replacing the MAF sensor with a new one had a high chance of fixing my problem, would be super easy to do, and would be relatively inexpensive. Should have been obvious since cleaning the MAF fixed the issue for several months. Anyway, didn't want to cheap out on this part with a random knockoff, so went with this Denso replacement (OEM was also Denso) and got it a pretty good price on Amazon compared to other places.Changed the MAF sensor which took all of 2 minutes, cleared the code, and have been good since. Car is driving better and no check engine light! Hopefully it sticks, but I'm sure the sensor had to be changed regardless and a mechanic would have charged at least triple. Very happy with the results!

Works good

My Prius had the engine light come on. I used my ODB tester and the code indicated and problem with th air flow sensor. I replaced it with this one and the car has had no problem for nearly 6 month.

I am elated with this part. It has been in my car about a week , now, and getting slightly better gas mileage. Before I purchased this I checked with the Toyota parts guy to be sure what is the correct brand of Mass Air Flow Sensor for my 2008 Prius. DENSO! My concern is this could be a cheap knockoff Chinese part, but, it sure isn’t acting like it. It took me about 35 minutes to install. Remove 2 screws and release the wiring harness. I used a screwdriver bit and a pair of pliers to remove and replace the 2 screws since there isn’t much room in front of the MAF. The dealer and my mechanic were asking me $225 just for the Denso part. I am hoping this is the real deal.
