    Hi, I have an 01 tacoma that is throwing a p0171 code. The code is for the mass air flow sensor. I've replaced it with a new factory Denso unit, but it still throws the code. Also, Even though the check engine light stays on, the truck runs as good as it ever has, nor has this affected the mileage. I replaced the air filter when I replaced the MAF and I just replaced the factory fuel filter with a wix unit last year. Any ideas? Any help is appreciated.
    Thank you!! :D
