MAF Sensor—How Cheap Can I Go?

Did you clean the mass airflow sensor wires that are buried down in the housing or just the amber temperature sensor bulb that is out in the open?

 

I'd only go with genuine Toyota.

 

Have you tested it yet..? MAF sensors are temperature (bulb) and air-flow meter inside the housing with two wires comparing data. Go cheap, if fails, go less cheap. ;p

 

Toyota or you will be sorry. Most get a few days to months out of aftermarket maf sensors before the fault returns and a mechanic diagnoses a bad maf sensor. Toyotas seem to be sensitive to maf sensor quality but most oem sensors last decades.

A few reviews of a best selling aftermarket maf, remembering most buyers review immediately and not down the road.

 

I'm in 100% agreement... All the OEM people have this bizarre cult like Dogma of paying a fortune for parts that might work just as well for 10% of the cost. What's more you're doing a service to the PriusChat community by testing the cheapest possible sensor out!

I know I've always tried to buy the absolute cheapest part I can find and it almost always turns out well and the rare times it doesn't I return it and get my money back, if it didn't take too long to fail. Then I buy a slightly less cheap one.

Don't listen to all the people that are wasting their money by being a part of an OEM cult.

 

wouldn't a salvage work?

 

Who's got time for all that these days? If you have, then good for you – go at it. Not only do I not have time to monkey with cheap aftermarket parts, but I don't have the time to do the same job multiple times. While changing the MAFS is not the most time-consuming or difficult job, I still only want to do it once.

The problem with that is you cannot be guaranteed you will get the same quality even from the same seller. These automotive parts are all fluid. It's kind of like buying from a dollar store. They never have the same thing twice.

 

The OEM seem especially overpriced for this part. The ”quality aftermarket” brands are a third of that price, ie Delphi and similar. I do not recommend buying any part from temporary/unknown brands on Amazon/temu etc.

I would try salvage, it seems based on one number that Toyota uses the same exact part on many, many models. I recently bought one at salvager for 10 euro from a lowish mile Corolla when I was there, just to have a spare.

 

What is the car doing that leads you to replacing the MAF? They do fail but that's pretty rare for Toyota.

I want to check power, ground, and signal circuits at the MAF connector (& the connector terminals for damage-looseness). Then see what a scantool reports for MAF readings.

Here's a thread that has "known good" MAF readings under different ICE operating conditions.
