Delphi AF10043 Mass Air Flow Sensor

I'm a procrastinator. My check engine light has been going on and off for like 7 years and 80k miles driven in that time. Finally bought this and - as a lady (cough!) - I was able to do this nearly all myself. So easy to change it was embarrassing. Hubby helped with the muscle for the old original MAF that was hermetically sealed with dirt and grime, but otherwise a simple 5-10 minute fix. A simple youtube search before digging in. It fits my 2003 Tahoe 5.3L LT with 165K perfectly. Runs so much better now, mileage has greatly improved (from 15.3 avg per gal all the way up to 16.5 so far - woah...). The check engine light hasn't come on once since the change.UPDATE It lasted 2 months...aaaand the check engine light is back on again - exact same codes as before I put this one in. Less than 1k miles and it goes out. Not Happy. Now I'm forced to buy another one. Should lower my 5 star to 1 but I won't. bah...

MY suburban was throwing a code for the mass airflow sensor. I replaced it with this one and the code has not come back. Super easy to replace this on my vehicle also. Only needed a flat screwdriver or nut driver.

Worked like a charm. Just like OEM and no more error code p0101.

2004 Silverado 2500hd 6.0 fit great , my truck was cutting out when I come up to a stop light / stop sign . Noticed my fuel economy got a little better to runs a lot smoother . Great purchase

Bought this in 2021 for $95 and right out of the box I was skeptical, had Delphi printed on the plastic, but not cast into the little aluminum plate. Worked ok (with no more P0101) code for about a month then crapped the bed completely. Truck would barely even run, thought I got a bad tank of gas at first, then came to find it ran fine again with the original MAF sensor (an actual Delphi that truck was born with). This is definitely a cheap chinese knock off! Will remove this review if I get a refund or exchange for real Delphi part.

The part did have the Delphi labeling but I was shocked to find "Made In China" on the MAFS.Part did work, verified with live scan data. On a 2005 Denali, mileage is now in the 13s. Hope I don't kick myself by not buying from a local parts house that offers lifetime warranty, this Delphi MAF sensor only has a year warranty. But like I said, 3 weeks in and still going strong.

Item arrived very quickly and in proper packaging. Despite it not being listed as fitting my 2004 Avalanche Z71, the part number did cover the replacement of the part number on my truck. I was getting P0101 MAF sensor circuit failure, P0171 lean condition on bank one, and P0172 lean condition bank two. I first ended up changing out the intake manifold gasket to eliminate that possibility since it is a known issue with these trucks, and cause the codes I was getting. If your intake gasket has a vacuum leak, your vehicle is getting more air than it thinks it is, causing the ECU to adjust fuel trim levels and resulting in the lean codes. It also will shoot the P0101 MAF code because the computer is reading more air coming in than what the maf is sensing so it triggers the code P0101 meaning that the readings from the maf were out of range for a period of time, usually four seconds, though there are other time ranges as well.Changing the intake gasket only got rid of my P0172 lean bank two code. So I ordered this AF10043 after seeing that the part #'s actually crossed. It took all of five minutes to change out. All you need to change these are an 8mm driver or socket, loosen the large hose clamps that attach the intake tube to the throttle body connection, the intake tube to maf connection, and the maf to air box connection. Unplug the maf sensor wire by simply pressing the clip and pulling away from the maf. If you have the double stage clip, there is a small shielding clip that slides over the tab of the maf so it wont accidentally get disconnected. To get the protecting clip off take a small flat head or pick ( I used a transmission line pick tool), get under each side of the tab and it pulls straight up, the clip will actually slide completely off exposing the tab to unhook the maf sensor.All of my CEL codes are now gone thanks to this product. I have verified my maf readings with my Bluetooth obd-II dongle in real time, and all are in proper ranges. I would recommend this product to anyone needing a new maf and I would buy again if I needed to.Thanks,

Same brand as the OEM, installed and it is working perfectly.
