    My 2008 Prius with 173,000 miles needs a new MAF sensor. The check engine light has been coming on sporadically for a couple of months. I cleaned and reinstalled it, and reset the code, but to no avail.

    A new sensor from Toyota is $140, and $90 from AutoZone. I picked up a “Ynovvo” branded sensor off Amazon with good ratings for $23. I haven’t installed it yet so could return it if the community convinces me it is asking for trouble to use it.

    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.

    Order online for $111 shipped to your door. Labor day sale from Toyota Corp and selected online Toyota dealers.

    Part 22204-22010

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