What is a MAF sensor?
A MAF, or Mass Air Flow sensor, is an electronic unit on a car's engine, which precisely measures the amount of air flowing through it.
It then sends vital information to the engine's computer, telling it how much fuel to inject into the combustion chambers. This allows the engine to work very efficiently.
Introduced in the late 60's, it is one of the most important sensors that an engine needs to work correctly.
Why you must clean it
Over time, dirt, carbon and oil from engine and EGR valve blow-by, gets deposited on the sensor. This causes it to miscalculate the correct air flow.
The engine's computer receives this incorrect information, injects the wrong amount of fuel, and creates various engine running problems.
Using a specialised MAF cleaner will restore the correct air to fuel ratio, and eliminate many of the related engine problems described below.
Catalytic converters and Diesel Particulate Filters also work more efficiently in a cleaner running engine.
Signs of a dirty sensor
Erratic idling, poor fuel economy, hesitation, stalling, limp mode, flat spots, engine warning lights, poor performance and emissions test failure, are all common symptoms of a contaminated sensor.
A poorly performing engine can simply be irritating, but also highly dangerous. Imagine experiencing an acceleration flat spot when joining fast flowing traffic, or overtaking a long vehicle on a narrow road.
Results you can expect
More power, stronger torque, better acceleration, smoother gear changes on automatics, cleaner exhaust emissions and curing of engine problems are just some of the benefits from cleaning.
Improved fuel economy will also save you a lot of money in fuel costs.
