MAF sensor questions for those who replaced theirs

it seams all first gens use the same MAF sensor so I have a few questions:

what brand did you buy?

what did you pay for it?

where did you buy it?

did you or anyone you know have any issues with any particular brand MAF sensor?

what is the OEM brand and part number the dealer sells?

do you know anything about which brands should be avoided?

and lastly (question for mechanics) is this an item that would have a good success rate with using used salvaged parts or don't bother trying?

 

I think the MAF actually changed in 99, just in case you go the used route.

 

hmm, ok

when sourcing the part using the Toyota part number it lists it as the same exact part for 4runners from 99-04 and tacomas from 96-04

the prices are just all over the map on these things from $800 for new factory original pat to $250 dealer replacement part (im assuming asin brand) and aftermarkets are from $200 down to as little as $20 for a cheap china made POS

used ones are averaging around $75-$60 but I thing that's just asking for trouble buying something like this used, if it has issues then your screwed.

if there was a sticker on mine its long gone or it has already been replaced sometime in the past but it shows my MAF sensor as part number 22204-75010 at the toyodiy.com website for vin number based part number search and according to a Toyota parts site it says it fits my truck but some sites say it doesn't fit my truck but toyodiy.com has been wrong about part numbers before lol.

I do know all the aftermarket ones I saw that showed fitment say they are for all tacomas from 96-04 and 4runners from 99-02 (I think)

 

I've done a lot of searches on these as well. what I have found is that the ones that are $800 are usually the ENTIRE thing. Meaning the sensor, and the small round housing the sensor is bolted onto. Then the lower priced ones are just the sensor itself, but priced based on brand. I have found several different brands that have given me success, the primary one being Dorman.

 

thanks, what is the price range you see for dormans?

and do all first gens use the same part number?

 

I've also been researching this the last few days, and here's what I've learned:

For the 2.7L, there is a pretty consistent difference in listings for 4x4 and 4x2 trucks. Some say that on my year ('96), the sensor alone is only replaceable on 4x2 trucks, while 4x4 trucks you have to replace the whole assembly.

Other sources say it's replaceable on both with the 22204-75010.

Many places list Hitachi as the OE manufacturer for this part. The Hitachi MAF0055 says it will fit rear wheel drives but not 4x4s. This is the 22204-75010 sensor.

The Hitachi MAF0053 is listed as the one to fit my 4x4, but it's the full assembly.

Either way, Rockauto is the cheapest I have found either one.

Personally, I can't imagine that they used a different MAF sensor mount on 4x4 vs 4x2 trucks, so I think either will probably work.

 

well what confuses me is the aftermarkets will claim the same sensor works for all 2.4 or 2.7 from 96-04 yet factory oem and dorman say the 22204-75010 just fits the 96-99 2wd 2.4 tacos as well as t-100 and certain year 4runners

and yes rockauto seams to "almost" always have the best prices but sometimes you can find a better price somewhere else so I always shop around to be sure.

sometimes you find it cheaper on ebay. I think its just Toyota employees stealing the parts and selling them but who is to say? I do know I have bought brand new factory oem parts there still sealed in Toyota box for much less then the going price fair rate.

I just bought a genuine oem Toyota tps for $25 on ebay

 

My apologies Keaker, I didn't see that you had a 2.4.

 

no apologies needed, it adds to the confusion because that is the same part number shown to "only" fit the 2.4L so ?????? wtf

plus when searching for parts many websites only show the sr5 as a 4wd truck when its an interior equipt package for "any" truck 2wd or 4wd.

anyway this leaves me having to search parts for the dlx version "which isn't my truck" in order to see the correct part numbers listed for my 2wd sr5 truck which sometimes are NOT the right part because they truly are the parts only for the base model trucks

 

keakar, I've always had good luck entering my truck's particulars (or VIN) into the search at toyotapartszone.com. They haven't sent me an incorrect part yet.

What symptoms are you getting that make you suspect your MAF needs to be replaced?

Mine is losing power and winding down on hills (as an LA native, I know this can't be your problem).

Just wondering what's led you to the same searches I'm doing.

 

+1

Great site. Toyota Parts of Dallas is also extremely friendly and helpful, although their website can be somewhat cumbersome.

 

lol, yep, no hills around here except the levees

I just have a persistent minor stutter/hesitation only between 1500-1750 rpm and nothing seams wrong with anything. replaced plugs and wires, injectors, about to replace TPS and IAC (IAC for rough idle situation) and TPS because its cheaper to replace then the MAF so im trying it first. if you asked me to describe it, it seams like it has flem in its throat with small throttle increase but then clears its throat and goes fine or if you give it more then just slight pedal it goes just fine so when driving like a grandma it hesitates a little just in that narrow rpm range.

smokin found in his high idle thread, that swapping his MAF did the trick for his hesitation so im following his lead and try that if I still have issues after replacing the TPS. in truth it will be the only thing left I haven't replaced anyway

 

And for cross-referencing with diagrams, I then search for the part number at villagetoyotaparts.com. It can be confusing to figure out which diagram goes with what, but it has more diagrams than anywhere else I've found.

If someone knows of a better site for parts diagrams, I'd love to know about it.

 

Between $30-70, depending on the source. My information shows that the sensor ITSELF is the exact same. The difference is if you try and get the whole thing, which is the sensor and the housing. THOSE are different.

See my post above.

 

When I run my VIN on Toyotapartszone, it tells me that the sensor alone part is not compatible with my truck. From what I can tell, they changed the actual sensor itself in 9/96. So for trucks after that, the sensor alone should work. For me with the early '96 truck, it seems I have to buy the whole thing.

I would love to be wrong on this and save a bunch of money, but I think I would be rolling the dice and might get a part that didn't work. If you have different info on the early '96 2.7, I'd love to hear it.

 

can you, will you, please share a link or website where they can be found for $30-$40? so far the cheapest dorman I can find is in the $85 range.

I found lots of cheaper aftermarket brands like Hitachi and Delphi for $50 and some china knockoff crap as low as $20 but I want a quality part that I can rely on to last

 

I think some of the cheaper after market ones will work with both engines and some of the better quality ones like dorman don't

go here and put in your vin number http://www.midatlantictoyotaparts.com/oe-toyota/2220475010?search_str=22204-75010

you can do the same at http://www.villagetoyotaparts.com/cars/TOYOTA/0/Tacoma/car-parts.html

from what I have seen on dormans website, seen here: http://www.dormanproducts.com/advance/itemdetail.aspx?ProductID=75828&SEName=917-913

so dorman says the dorman MAF sensor 917-913 that fits my truck is not the correct part you need for the 2.7L engine in your truck but the websites selling the dorman MAF sensor 917-913 say it will fit the 1996 2.7L engine but only in 4runners

I would trust what bama says on this because he is an experienced guy who knows what he is talking about.

is there any number at all on your old one you can go by?

 

Yes, the number says I need the full assembly. Bama says I can make do with the sensor only. So that's why I'm still on the fence.

 

well the full assembly is nothing but a round housing, it serves no purpose but to hold the MAF sensor centered in the airstream so its just silly to pay to change that part unless something is wrong with yours like stripped screws or its all corroded.

no need to be on the fence about that, just buy the sensor because that is all you need.

 

I'm concerned that either the newer sensor will be the wrong shape to fit in the hole on the housing I have, or they changed something with how the sensor sends signals to the ECU, or that the plug might be different with the different sensors. Lots of variables - it's not as simple as it seems.
