What tool do I need to remove MAF sensor?
You need a T20 tamper proof Torx bit (inset upper left and lower left) to remove the mass air flow sensor from its home in the intake pipe (yellow arrow). It’s typically easier to pull the sensor out of the intake tube first, and then disconnect the electrical harness.
How do you bypass MAF sensor?

DO NOT USE WD-40. Use a cleaner that is meant for electrical parts. Brake cleaner is essentially the same stuff. I’ve also used something called ‘thottle body cleaner’ whose label indicated it was safe for cleaning MAF’s.
How does the air flow meter work on a Toyota 22RE?
As such they lack a mechanical carburetor and instead split the function of the carburetor into three parts, namely the Air Flow Meter in the air cleaner box, the throttle body and the fuel injector. The air flow meter uses a flapper vane and temperature sensor to detect the amount and temperature of the incoming air flow.
Is there a mass air flow sensor on a Toyota pickup?
Factory components aren’t designed to maximize performance, though. Install a Toyota Pickup MAF sensor from AutoZone to improve your air-to-fuel ratio and enjoy more MPG wherever you drive. An aftermarket Pickup mass flow sensor reads a higher volume of air flow coming into the engine.
Why are air leaks bad on a Toyota 22RE?
The reason air leaks are bad is that the engine ECU reads the incoming air flow from the AFM.
Where is the AFM located on a Toyota 22R-E?
While this information is based upon the AFM system in the 22R-E engine, most of it applies to other Toyota EFI engines. For specific information, be sure to consult the service manual for your model engine. On the 22RE engine, the AFM is located atop the air filter box.
