Delphi AF10043 Mass Air Flow Sensor

OEM. I was able to get it to work without any problems. My first wrangling of mine came out EXACTLY like the original one I took out of my 2004 Chevrolet It arrived well-packed and clean, and it doesn't require any further troubleshooting because there are no codes afterward. Just remember to disconnect the negative battery terminal for 10 minutes in order to "reset" the relearning process on The battery was unhooked before I began the work, and when I was done, I simply connected it back up and did the job. A brief update We're still going strong two years later!.

The MAF sensor is a Delphi product and worked perfectly until I went on vacation. The OEM Delphi sensor then started After getting the aftermarket one that was slightly cheaper, I stopped at a parts store. The code was given to me no more than 5 months later. I read some forums and talked to some mechanics and found out the solution was to go back to Delphi products. A little online searching found this one which was a lot cheaper than the local auto parts store plus the clickable coupon made it an even better deal. My vehicle has been in use for 3 months now and has not caused any problems.

I took out my original unit that lasted 13 years and 140000 miles and replaced it with an exact same model. Also, your battery has to be disconnected from the negative side, then you have to loosen a few band clamps and disconnect the engine You need to pull out your old Delphi (Original Equipment) unit and replace it Replacing the old one, tightening the band clamps, replacing the frame Attach the negative terminal of the battery to the harness. Before installation it's a good idea to clean out the air box and replace the air filter too, then start the engine, the if there was a PO101 error code it would be automatically wiped by disconnection of the battery. The engine will have more pep, it will eliminate the throttle stumble, almost stall at idle problem, and erratic idle issues, and it will also It is a great plus to have the 2500HD with both the 6liter and 4liter engines The rear end of a 11-ton truck. For 80 bucks I bought a like new, high performing vehicle that in my truck will pay for itself in reduced gas mileage within a month. It used to be not good on gas anyway, but now it runs as smoothly as a sewing machine, like new for 80 bucks!.

With 287,000 miles on it, I have a 2001 Chevrolet Suburban. It has been a while since we've had any pinging or slow acceleration issues. problem of lean conditions started popping up on both the left and right banks in the new CEL codes we noticed in the past few months. In this case, a vacuum leak is indicated by this condition and we addressed these problems by replacing the intake manifold gaskets along with the EGR tube and gaskets, as well as the exhaust gaskets based on an extensive smoke test that revealed leaks everywhere. However, despite improving performance and showing no further leaks in the smoke tests, the vehicle continued to periodically display codes P0171 and P0172. Due to the original O2 sensors being in the car, we decided not to use those, and installed AC Delco O2 sensors instead. Our testing found that the P0171 and P0172 codes persisted, although we did notice a slight improvement.

Just for good measure, and based on the symptoms, we inspected the fuel pressure and found that it was decreasing towards the bottom The lean condition stuck even after we replaced the fuel pump and an AC Delco model. Fuel pressure and performance improved after the change, but still the system was lean. I found some articles that, although everything I had replaced was likely the cause of this condition, others had replaced their MAF sensors for new models and their issues were resolved. I decided to give this product a try and found it on Amazon for a much lower price than the local auto parts vendors. I received the new Delphi MAF sensor from Amazon the same day I ordered it, and it took less than 10 minutes to install. In the process of doing it, I had removed the negative battery cable. When I had completed the replacement, I reconnected the vehicle's wiring. After driving it for a while, I noticed that the Long-term improvements are beginning to show up We are operating in the 5-point range with our term fuel trim now having dipped down from 30 to 5 The recent range hovers close to 0 recently, it's been in the 7 range The range is 3 to 5. It's not only not going over 25 that is resulting in the P0171 and P0172 conditions no longer triggering CEL alerts - but also not going over 25. However, it turned out to be an expensive exercise of the hated "replace-with-what" Here's the - The parts of Take a look- As you know, Let's get started Replacing this MAF sensor was a lucky approach, as the problem was finally resolved. Although I was very careful to provide schedule maintenance for the latest years of my vehicle, I am almost certain that some of its original parts had worn out. I also know that the replacement of this MAF sensor was the final component that implemented a reliable performance level for my vehicle.

It is recommended that you use the factory parts for engine control systems for vehicles, rather than aftermarket parts, unless you are building a high performance vehicle with expensive components. The air flow meters and fuel pumps are of particular importance. With this new air flow meter, I've been able to restore my part throttle acceleration and eliminate any bogging that would otherwise require me to accelerate harder in order to create a downshift. The reading on my old meter was off just enough for the computer to think it was pulling in less air than it was actually ingesting, but the reading was The problem is that this sensor didn't always agree with other sensor readings and would set a code occasionally. The computer didn't know how much load I had on the drivetrain, so when I hit cruising speed after hard accelerating, I felt like I had a street shift kit in an old Chevy TH350, almost like in a heavy-equipment vehicle. All the issues associated with the old airflow meter are now gone because the new airflow meter has created harmony.

I had a bad MF last year, so I cheaped out and bought the cheap knockoff from China. A few months ago, I had no MAF codes and bam, they all came up at once. I did the test again, and yes, another bad MAF. However, this one had only 4000 miles on it. It had 265,000 miles on the original maf, while it had 4000 on the replacement. My opinion is that the wasted time and money were not worth it.
I got this one this time and was able to notice a difference in the quality just from looking at the exposed components. OEM quality is a real thing, and it's a factor you want to consider when buying sensors or parts for a vehicle that you will keep and drive yourself. The only problem is I am only on for a little bit. I have no doubt the connection.
