Where should MAF be located?
Most agree that the MAF should be placed where the smoothest and most consistent air flow is. Typically this must be before the turbo inlet or after the intercooler near the throttle body. On an aftermarket “cold air” intake it is best to allow around 12 inches of straight, unobstructed tube to place the MAF in.
How far should the MAF be from the throttle body?
Registered. It helps the system to have some straight tube in front and after MAF and it is not too close to the TB. The engine takes air in “waves” resonance effect cause by the valve open and close. To have a correct reading at the whole rpm-band I would suggest a 4 inch straight after the MAF and before the TB.
What happens if the MAF sensor on a Camry goes bad?
A bad mass airflow sensor can leave your Toyota Camry’s engine running rough, or even inoperable. A MAF sensor measures the density of the air entering the intake manifold. It passes this information onto your Camry’s ECU. The ECU uses this information along with other sensor data to control the amount of fuel that enters the combustion chamber.
How does the MAF work in a car?
The hot wire is heated with an electrical current. As your vehicle accelerates, the throttle opens, allowing the air that enters the engine to pass through the MAF. The air cools the wire, so as more air passes through the MAF, more current is needed to keep the wire hot.
