I had purchase this after market for my 2006 Toyota Highlander Hybrid as the add says it matches. I had fit it as instructed and even reset the "check engine" light. Every 60 miles or so the check engine light kept coming back so had to take it to the dealer who replaced the MAF with the OEM part and since then the check engine light has gone. So to me I paid for a part which is not of any use.

Started to notice a little hesitation on my pickup. After the usual suspects were ruled out, plan B led me to the Mass Air Sensor. Easy to order, quick delivery, and perfect fit. She is running so quiet now, I think I can hear the neighbor’s Ford rust.

... next on my 2005 Volvo XC70 will be to replace gaskets on the intake manifold and throttle body and inspect the entire air intake system for leaks. At this point this MAF sensor works fine as far as I can tell... And as I say I'm just chasing a vacuum ... I think leak

I picked this up for my 2009 Prius. After multiple attempts at cleaning my OEM mass air flow sensor with 235k miles, I decided it was time to just replace mine to try to fix the check engine light and worse than normal fuel mileage. The car was acting up and throwing a CEL for a month or 2. I cleaned the mass air flow sensor and throttle body with the CRC kit you can buy in stores. At first I thought it worked, but ultimately the CEL came back. I tried cleaning the MAF sensor again, CEL again. People say "they never go bad". Well, they do.I gave up on cleaning and just ordered this because of the price and positive reviews. I inspected it upon arrival and saw some slight differences but gave it a shot anyway. Low and behold, no CEL and the car not only runs better, but I gained back the MPG's I had lost once the CEL started popping up.Happy with my purchase, I saved a decent amount of money and my car is running great again!

Funciona bien, pero tuve que desmontar el sensor del tubo, porque el ducto del aire es un poco mas grande. Espero dure mas que el anterior (de otra marca) que se descompuso a los 4 meses.

The sensors didn't look exactly the same as the one I pulled out of my truck and when I first installed it and started the truck, it ran worse with it than without. So I was disappointed at first BUT I found the following procedure in a forum, it was mentioned for Nissans in general and it worked for me (I am not a mechanic and you should not listen to my advice).Directions: --- "check if ECU need to perform “MAF learn” procedure on your engine.This is definitely the case on my Nissan and procedure is very simple to follow (essentially: warm up, stop, disconnect MAF, start the engine and let CEL to get on, re-connect MAF, clean code, let vehicle idle for 15 minutes not touching accelerator). It may be different for another car, but should be possible to find on Chevrolet-specific forums." ---I bought a cheap OBD2 reader to read and clear the fault code. After 14 minutes of terribly rough idling and nearly sputtering out numerous times (I did not touch the accelerator once) it evened out and is running fine now.
