Delphi AF10043 Mass Air Flow Sensor

Worked perfectly. This one was EXACTLY the same as the original one I pulled out of my 2004 Chevy Silverado. Arrived packed well and clean, and no codes afterward. Don’t forget to unhook the negative battery terminal for 10 minutes to “reset” the relearning process in the computer. I unhooked the battery prior to starting the work and by the time I was done I just hooked it back up and was good to go. UPDATE: 2 yrs later, still going strong!

The service engine light came on and I couldn’t get it to go off despite several troubleshooting attempts. When I went to replace this sensor I discovered it was exactly the same as the original GM part. I paid nearly half for the part than I would have through a local auto parts store and, so far, I think I solved my problem.

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

Was a direct fit for my 2003 2500hd

This was identical to the sensor that was already installed on our 2006 Chevy Tahoe. Installed it and the check engine light turned off after probably 15 minutes of the car running. We had a mechanic check for the vacuum leaks and make sure the exhaust manifolds werent leaking. He said this was the next step and quoted us $300. We have a K&N filter so we will see if the oil causes any issues but I havent oiled it since we put it in.

Lots of cheaper MAF sensors are available, but this is not something you want to scrimp on. I use a ScanGauge to monitor fuel trim on the 8.1 Vortec motor in my motorhome, and it was starting to run lean over time. A lean condition can ruin a perfectly good motor, so I cleaned the old MAF sensor. That helped a little, but replacing it put everything back into the normal range.

Had a MAF code pop up on my 2001 Chevy 2500 Suburban 8.1 LT. Had a rough idle. Cleaning it with MAF cleaner did not work.

I ordered this one after installing an aftermarket intake on my 06 Sierra. When I was installing my intake, I kind of bent the honeycomb portion of the original MAF sensor and then my check engine light would sporadically come on. Installation was easy and there was a rubber gasket that was on the old one that needs to be transferred in order for it to work. Check engine light doesnt come on anymore and the replacement took about 10 minutes.

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!
