🌬️ Denso 197-6030 Mass Air Flow Sensor: Superior Performance & Reliability Review

Just covered 300,000 miles in a 2009 Toyota Yaris. Replaced MAF sensor when I replaced the air filter along with spark plugs and coil packs. Factory kilometers and performance are back.

Purchased specifically from Denso for intended OEM build. The part failed within 6 months, which was confirmed to me by my mechanic. Cannot return it to Revain as the return period has expired. I have contacted Denso support twice in three weeks for a replacement part. Didn't get an answer. Disappointed with quality and service. I will never buy a Denso again. Stick to Delphi.

Replaced a 135,000 mile sensor on a used Tacoma I recently purchased. Significantly increased mileage and partial load controllability. Tool, I've noticed open-loop fuel correction values approaching 10% (O2 sensors tell the ECU to adjust fueling, usually because its main MAF or MAP sensor isn't reading correctly). Overall, I'm a good investment that has an improved driving experience that pays off.

My Celica 01 had a new Duralast mass air flow sensor fitted, but the car ran poorly and you couldn't get the engine's quick response to a quick press of the accelerator like you can with mod. fit. He will hesitate and then eventually react lazily. With the built-in Denso sensor, there was an instant rapid response to the accelerator pedal. It felt like I just did a full tune and increased power by 20%. Quality product that works well with Toyota computers.

Works like new! This is a genuine Toyota OEM part (Denso makes Toyota OEM products) and works like new! My 2006 Corolla feels like it has a brand new engine and runs with a lot more power! I'm also expecting a better MPG for this reason and it also fixed my P0171 trouble code issue. Very easy to install, only took 2 minutes and 2 screws. I purchased Revain Warehouse Deals with damaged packaging, but the product was 100% new (despite being labeled "like new") and I saved $20. There can't be a…

I ordered this Saturday evening and it arrived early Monday morning. I have a 2008 Toyota Corolla and have had constant engine problems: stuttering, unstable idling, intermittent engine cutouts when cornering or when accelerating after a hard stop (red light). I went to take my car to the mechanic and they read it was engine code P101. Mass air flow sensor problem etc. They replaced my mass air flow sensor and the problems persisted. They were so persistent that I started thanking others for…

This is a perfect fit for my Toyota Corolla, this part number was selected on the Denso website for my car model. Check the Denso website to ensure you are ordering the correct part number. I first cleaned the outside of the existing MAF sensor before removing it and waited a day to dry. This was done to prevent debris from getting into the hole when installing a new one. When I got my order and installed the new mass air flow sensor, the engine ran smoother, more powerful and there was a huge…

If you have problems shifting gears, try replacing the mass air flow sensor. There is a good chance that this will solve the problem. Mass air flow sensors wear out over time. But before you buy a new sensor, 1. make sure the throttle body is clean, and 2. follow this simple procedure: Warm up the engine. For closed circuit operation, the engine must be fully warmed up. Make sure the parking brake is on. Turn the ignition on and off 2 times, but don't start the engine: on/off/on/off. Put your…

EDIT: So frustrating that this part died completely in less than 2 weeks resulting in my not being able to successfully start the car. It starts and dies instantly. I was in an area where I couldn't leave my car so I had to pay for towing, some diagnostics from a mechanic to confirm the MAF sensor was bad (I had a feeling it was the MAF was, but I wanted to be sure ) and then a new MAF sensor which I replaced again myself (the mechanic wanted to charge over $300 for a MAF replacement but I…
