Delphi AF10043 Mass Air Flow Sensor

This is an OEM Delphi replacement MAF. You can pay less for the Chinese garbage and be frustrated when 80% of them dont work or fail early, or spend a bit more and simply solve your problem. I hesitated to even call my original part bad... Id get a code and check engine light maybe once a month and it ran fine otherwise. Replaced with this new Delphi part, and no more codes in months. My original factory part was also Delphi, and lasted 250,000 miles. I expect this will as well... Which makes it a better value that the cheap ones that seem to last a week or a month if they work at all.

This MAF senor is a Delphi product and fits like youd expect. While on vacation the OEM delphi sensor starting throwing a code. I stopped at a parts store and got an aftermarket one that was slightly cheaper. It lasted all of 5 months before I was getting the code again. After reading some forums and talking to mechanics I discovered the way to fix it was going back to a Delphi product. Little online searching found this one which was a lot cheaper then the local auto parts store plus the clickable coupon made it even more of a bargain. Been in the vehicle 3 months and no issues yet.

Exactly as I expected it to be, mine tested fine so Im not sure what happened to the other reviewers product. It is super easy to damage a MAF sensor, even abnormal moisture in the air while you are installing it has caused issues on some of my other vehicles. Its a very sensitive piece of machinery but that is expected. Very happy with mine and it is still going strong for the last 3k miles, will update my review if I run into any issues.

Was a direct fit for my 2003 2500hd

This is exactly what I needed! Engine quit acting like it was going to die when I started it up in the cold. No more hesitation or bogging down while under load or acceleration. Check engine message- “POOF” -gone. Should have replaced my airflow sensor years ago. Little pricey, but it worked and I couldn’t be happier!

Extremely easy to install. It was an exact fit for my 2002 GMC Sierra. It fixed the issue with the codes. I use the bluedriver to find what was causing the code and it actually recommended buying this part.

Bought 8/7/22 Had some hesitation on hills Was told replace the MAF sensor. Found one on Amazon for good price. Supposed OEM equivalent. Was easy to install. Turned out wasnt the problem. So I left it installed and kept the old one for a back up(which is also a Delphi with a lot of miles on it and at least 7 years old). 12/27/22 Last week truck set p0171 and p0174 codes. Running terrible! Or barely running. So I put the old one back in all the fuel trim levels came back to normal and check engine light turned off after driving a couple miles.1/5/23 Contacted Delphi for support waiting for reply will update review if/when I get a reponse

It works well in my c5 z06 when I had it installed.

Check engine light kept coming on

This was easy to install (about 5 minutes, if that). It was an exact replacement for the original one from the factory on my 2003 Silverado 1500HD. It immediately cleared the engine warning light and Ive had no problems since I installed it.
