system has three main parts: air filter, mass flow sensor and throttle body. a. Air Filter An air filter is an important part of a car''s intake system, because it is through the air filter that the engine "breathes". It is usually a plastic or metal box in which the air filter sits. The air filter''s job is to filter out dirt and other foreign particles in the air, preventing them from entering the system …

Normally, the MAF is located next to the air filter with an intake muffler or pipe between it and the throttle body housing. For a better throttle response, move the MAF next to the throttle body housing. This will put the order of objects: air filter, intake muffler, MAF then throttle body housing. This eliminates the air mass from the intake muffler and let the MAF respond faster …

P2281 OBDII Trouble Code: Air Leak Between Mass …

+

The P2281 diagnostic trouble code is an indication of the existence of an air leak between the MAF sensor and the Throttle Body. The MAF sensor uses an electrical wire to make a determination as to the amount of air that is being permitted to enter the air intake system. This information is sent through this wire and delivered to the powertrain ...

DIY: Mass Air Flow sensor + Throttle Body cleaning | …

27/04/2018· Mass Air Flow. Electronic fuel injection systems using MAF metering have a mass air flow sensor. The MAF sensor is typically found in the air intake tube, before the engine’s throttle body. The sensor measures the air coming into the engine, and the EFI system’s computer uses that information to determine how much fuel to deliver into each cylinder. Now, …

30/04/2019· When the air passes through the mass air flow sensor, it is calculated at a specific volume and if there is more or less air than the calculated amount, it can cause major issues for the motor. More air can cause a car to run lean which means that there is too much air and the fuel is burning too quickly. This means the combustion will not have as much power to move the piston. Running lean can also …

Situations where MAFs read unreliably due to reversion can generally be greatly improved by moving the MAF further from the throttle body. Increasing the volume of the intake between the MAF and the throttle body is also effective at smoothing out the pulses of air coming from an engine with a radical camshaft. It is normally possible to get a reliable enough MAF signal in …
