Better than trying to clean the old one!
Pretty easy to install on my Prius! The old one was so dirty that I do not think trying to clean It would’ve made a difference. Immediately after changing it and the air filter, I drove from Las Vegas to Los Angeles. On the way home after the computer had adjusted to this new part I got some of the best fuel mileage The car has had in 10 years! Definitely worth the price!

So Far So Good!
I installed this on my 2003 Jaguar S-Type V8 4.2, along with a new set of ignition coils and it cured what was ailing my Kitty. Was it the main reason for faults and rough running, maybe not but it sure hasn't hurt it any. If it didn't work then my faults would be lighting up my dash.....which it is not. I keep my OEN in the trunk just in case.

Does NOT work on a 2001 4runner as stated
If you get this to replace your one in your 3rd gen 4runner, dont. It doesn’t work it’s as if you don’t have one at all. OEM from another truck works fine, this one does not. DONT BUY

Working great
Mine had o-ring and was easily installed. Like so many sensitive electronic devices if you drop it you can easily damage it. Also you need to check your wiring for damage and fuses. These still use a heating element to check the amount of air entering the engine.

Amazon said that this fit the 2000 Tundra V8, but it doesn't. Please correct that.

Reset the errors with my scanner. Unplugged cable(s) to the battery to reset errors also. Errors were generated after acceleration testing to intentionally induce P0171 and a few other codes that were intermittent. After battery reconnected ... the car quite lethargic. After 5-10 minutes ... and ECU at 100% ... running better. This expected and yet the car still difficult to accelerate from a stop ... hence the testing. Took a guess and figured the sensor. Disconnected the battery and installed the sensor. Reconnected the battery and started the engine and drove immediately. This time no 5-10 minutes lag time to get the ECU lined up to 100%. This is when I knew it being the sensor. It is usually suggested the car runs 'rough' after a battery disconnect. This did not happen after the installation. It's been a few weeks since. The car is a 2000 Toyota Echo.

Probably works well when used in the right application. Guarenteed not to work with your 1JZGTE swap 👍
