Operating at 12 volts with ±2% accuracy and capable of withstanding temperatures up to 392°F, it offers plug-and-play installation with immediate improvements in idle smoothness, throttle response, and emissions compliance. Trusted by professionals and backed by Delphi’s decades of expertise, this sensor delivers reliable performance and durability. ## Description More commonly known as MAF sensor or air meter, the mass airflow sensor has one very important job; measuring the amount of air entering the engine for an optimal air-fuel ratio. Without this information, the ECU will not be able to accurately control fuel injection, resulting in an engine that will either idle roughly, or worst case, not at all. But don’t worry! We’ve been producing OE MAF sensors since the 1970s. Review: Fixed My Rough Idle Right Away – Plug and Play - I replaced the MAF sensor on my vehicle after dealing with a rough idle and hesitation that cleaning the old sensor just wasn’t fixing anymore. I went with the Delphi AF10043 since Delphi is an OEM supplier, and I’m glad I did. Install was straightforward. Unplug the connector, swap the sensor, and that was it. No relearn procedure needed in my case and the check engine light cleared immediately after a short drive. The difference was noticeable right away. Idle smoothed out, throttle response felt normal again, and the hesitation on acceleration is gone. Fuel mileage even seems a little better, though it’s still early to say for sure. Build quality looks solid and matches the original sensor that came out. Fit was exact and the connector snapped in tight with no play. It didn’t feel like a cheap aftermarket part, which was important to me since MAF sensors can be hit or miss. I’ve had it installed for a few weeks now with no issues, no warning lights, and no weird drivability problems. If your symptoms point to a failing MAF, this is a solid replacement and cheaper than dealer pricing. Wouldn’t hesitate to buy it again. Review: Within any process, there will be duds - worked great for me - The negative reviews had me questioning this with stories of “Chinese junk,” open package and used status. The sticker that is supposed to tear when you open it, doesn’t, so the scam potential from a returned item is possible. Side note: I’ve only gotten one item where someone returned only half the item from the box. Losers will be losers. The MAF was new in the box and unused. 15 minutes later, it’s in the truck. No more P0101 codes or any other issues. I put the thing in, cleared the stores code, drove to get the emission testing complete and it passed with no issues. ## Features - Fit type: Vehicle Specific ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000CGFHBY | | Best Sellers Rank | #22,447 in Automotive ( See Top 100 in Automotive ) #19 in Automotive Replacement Mass Air Flow Sensors | | Brand | Delphi | | Brand Name | Delphi | | Customer Reviews | 4.4 out of 5 stars 1,846 Reviews | | Global Trade Identification Number | 00689604153185 | | Included Components | Mass Airflow Sensor | | Item Dimensions | 5 x 4 x 6.5 inches | | Item Type Name | Mass Air Flow Sensor | | Item Weight | 0.01 Ounces | | Item dimensions L x W x H | 5 x 4 x 6.5 inches | | Manufacturer | Delphi | | Material | Metal, Plastic | | Material Type | Metal, Plastic | | Maximum Supply Voltage | 12 Volts | | Measurement Accuracy | ±2% | | Model | AF10043 | | Mounting Type | Flange Mount | | Output Type | Analog, Digital (Push Button) | | Specific Uses For Product | automotive air-fuel ratio measurement, engine performance monitoring | | Style | Modern | | Style Name | Modern | | UPC | 689604153185 | | Upper Temperature Rating | 392 Degrees Fahrenheit | | Warranty Description | Delphi warrants the products will be free of defects in materials andworkmanship.
