MAF problem on TRD Filter Help

First off, welcome to the forum.
Second, I'm sure there's plenty of members on here with stock air intakes they could sell you for far less than $500. If you really want to go back to stock just post in the for sale section that you're looking for one.
Apologies, you've been here longer than most...just don't frequent much.

 

No offense taken. I don't go all in on who posts what, how many or how long. Forums are are reference for me more than a social outlet.

That is a great idea. how ever I would not know if ALL the little parts and screws would be there. I did notice a big hole in the fender well. I am guessing that's where the stock unit gets intake. Seems like a strange place to suck in air- where the wheels are moving and creating dusty turbulence.

 

Thanks for that youtube video dude! After Tennessee gets off its menstrual cramps of being nice one day to snow the next I'll check it out if that might be the problem too. I've been doing some research on my trd intake and found out AEM made the 2010's intake system, had no idea thought it was AFE. Read on another site about an FJ cruiser doing a comparison of the AEM TRD Intake and the AFE TRD Intake and said on the dyno that the AEM TRD runs leaner, kinda weird but interesting.

 

There aren't many little parts to the stock intake... it's a filter, 3 piece tubing/box and everything else is already being used on your aftermarket intake.

I'm sure you can find a stock set up here for under $100 (at most)... That hole is in fact where the air is coming from. But it's not as dirty as you may think because the wheels are not exposed to the hole due to fender lining. It's actually relatively sealed in there except for the ventilation slats at the bottom of the wheel well towards the front bumper.

And to get back onto topic...

I have put almost 40K miles on my TRD 1st gen intake and about 10K since I last oiled it... No problems.

The stock intake is dual filtered with the first removable filter being thick for it's off road use where the truck will be sucking in more dust, dirt, sand etc... It is also slightly more restricting because of that. Where aftermarket filters don't give as much protection but it's not necessary for vehicles that don't see much dirty conditions.

The stock intake on my Impala isn't dual filtered nor is the filter as thick as the stock was on my X-Runner, Same goes for my previous BMW.

 

Agreed. I've always been a K&N guy, have one on my Honda and one on my Kawi for years and never have had any trouble. I think like you said probably cleaned the TRD one on my Taco wrong. That link helped out with the difference in the dry air filters and the oil kind so thank ya man! I'm tempted of getting the dry filter and see how it does. Since I found out that AEM made my year of the intake system, and found they have a dry filter, I'll probably give them and AFE a call and see if anything will fit in the box.

 

Not angry at all about it. I just get tired of misinformed people suggesting bad products. Its a scamming industry and it is doing its job very well of scamming people because some people still buy into it.

I may come off as an ass but it is not directed at you. More to the company's like K&N that make it sound like a miracle product when actually it is bad for your truck.

 

Been doing some research on the side Read about K&N Filters on small aircraft forum. Funny. The same arguments for and against. Any arguments there "for" there are good enough for me. I can see where manifold pressure would increase at higher altitudes using a K &N with more airflow in an aircraft engine especially as as the filter oil wears down a bit. But I don't see a real danger there because maintenance is not ignored in that environment. Engines have been torn apart and no issues reported. If it's safe enough in that world, its certainly good enough for my truck.

I will leave mine in the truck. I don't ride in dusty areas or land on dirt.... intentionally.

 

Are you still getting MAF check engine light issues? I have an 07 and just installed TRD CAI. I just replaced my MAF as well. I've been cleaning it for the past couple years but it finally gave out, felt it while driving up a hill lacked power. I had a Tru-Flow CAI system before but it didn't pass smog due to not having the CARB EO number sticker. Tru-Flow went out of business a few years back so I installed TRD instead that's CA legal.

I do notice that when I installed it. If you push the main black air inlet tube all the way as shown in the instructions. The red silicon coupler with the plastic nipples for the breathers do get blocked. I've seen the Youtube video where they suggest cutting the tube. I'd prefer to not to shorten the tube but just wiggle it enough to the left that it doesn't cover the 2 important holes. Just remove the 90 degree nipple to view inside with a flash light. Then tighten it in place when you can see it's not being blocked by the inlet tube. I suspect that yours might be blocked that's why it keeps throwing the code. Also listen for a 'hissing" noise after you turned your engine off, if your breathers are blocked you'll hear the noise.

 

It hasn't gone off yet again, crossing my fingers. But that's some good advise, do you have a link to the youtube video? My TRD intake was on the truck when I bought it so I don't have the instructions to it. Wish the guy before put it in the glovebox.

 

Here's the youtube video link to where they suggest shortening the tube.

There's no need to shorten the tube in my opinion, just move the tube till it's not blocking the 2 flow holes then tighten up the clamps. The instruction manual doesn't have much in it except for installation steps. There's wasn't much to it.

 

Cool deal thanks for the video man. It actually went out again Friday. Took it back to Toyota and told them it was the mass air flow sensor again and they acted like they didn't believe me but they called back and said that it was the mass air flow sensor. They said it wasn't the airfilter that caused it . So they are going to call the corporate technicians on Tuesday and see why it keeps going out. I might just reassemble the intake system and make sure the tube isn't blocking the holes if they can't figure it out.

 

Just got back from them fixing it, now they are telling me it is the filter. I'm almost at the point of just selling the TRD intake system and going with something else. Any suggestions if I do go with another intake system?

 

It amazes me that Toyota would put their name on something and not support it or especially admit that it causes issues. Seems like something they should have checked out before releasing to the public. I also wonder why they changed the design, I never read about anything like this happening with the 1st gen TRD/AFE stage 2 intake.

 

Exactly, it's puzzles me that Toyota did that. I wish they would go back to the other design that they had. I just broke down and bought a new TRD air filter, hopefully that'll stop it from happening but if it does happen again they can't say it's the filter.
