Have had some issues lately and the tech at my local Lexus says the culprit is a faulty MAF. I have 110,xxx on the odometer.

Do these typically go bad after 100k miles or would a cleaning suffice? I'm only asking because it's $440 for the dealership to order and replace the part. Seems excessive when I can buy one online for $140 or buy a can of cleaner and clean it.

What issues were you having, it would help a lot more and maybe some of the guys in here could help. Im at 120k and my MAF is fine, I just clean it every so often

It was running lean enough to throw a code, and apparently lean enough to prevent the car from using first gear in auto mode. The tech cleared the code and first gear appeared, the code came back and first gear was lost, several times. Why that's a thing, I'm not sure. lol.

I asked them to check if it's an OEM filter, and it is. Just wanted to rule out a filter full of oil mucking up the sensor.

Limp mode you loose first gear, just clean the maf what codes were you getting. Go and buy a maf and put it in yourself it is very easy

I agree. Just buy some MAF cleaner spray and clean your existing MAF first and see if that helps (unless the dealership was certain that your current one is shot). If you can, take pictures before/after you clean it for the forms. That way, if the cleaner spray works, we'll know what a MAF looks like when it's "too dirty." But if it's an electrical issue or if the part just failed I guess there's no point. If you end up needing a new one I'd install it yourself. Don't forget the discount code CL5 on mylparts.com

MpKSonic, in the Mother of all ATF thread you mentioned there was fluid dripping from the back of your car. Did you identify the source of the leak? I figured I'd bring it up here since the other thread was kinda getting off topic.

It's already been said, but definitely try cleaning it first. I just cleaned mine yesterday. It was super easy taking about 5 minutes. Luckily, mine was not dirty, but I still hit it with MAF cleaner any way.

Every time you change you air filter you should clean MAF senor get a can Of CRC MAF cleaner. It's super easy DIY 20 to 30 mins from start to finish taking you time.

yeah, I guess your statement is a bit more accurate... it probably takes 20-30 min to clean from start to finish. I said 5 min but I was already in the process of installing the RR-racing tuned intake system. The way the MAF is situated, it would take a little bit more time to gain access to the two screws that hold it in.

I have RR RACING Tuned intake system as well with this setup it's now 5min job lol. No OEM air box to deal and intake tube etc.
