We recommend Archoil AR2810 MAF Cleaner as it contains 300ml of the best solvents available for precisely this task.
#MASS AIRFLOW CLEANER PROFESSIONAL#
In contrast, professional MAF cleaners have a blend of multiple solvents specifically for the type of debris that needs to be removed, making the job a little easier. Also, remember that they usually contain a single basic solvent. Standard electrical contact cleaners are also effective, but ensure they do not leave any residue. The solution is to clean the MAF at each service schedule with a designated MAF cleaner.

An error code or warning light will only appear if the unit has failed completely. Unfortunately, even the most modern ECUs cannot detect this degradation of performance. This can result in poor engine running, hesitation, increased emissions, reduced MPG, and so on.
As a result, this oil and debris can make their way onto the sensor, affecting the accuracy of the airflow signal to the ECU. Over time, the hot wire on the sensor can accumulate debris, dust, and sometimes oil particulates, especially if an aftermarket filter or induction kit is fitted, as the filter is typically coated with an oil to trap fine dust. This subsequently changes the voltage signal (normally between 0 and 5 volts) sent to the ECU. This pre-heated filament, when hit with air, cools and creates a change in electrical resistance. The most common MAF type is the hot wire. However, Air Intake Temperature (IAT) sensors and, in many cases, Mass Pressure (MAP) sensors are still required. This helps the ECU better respond to differences in air density from changes in temperature and air pressure. MAFs got their name because they are designed to calculate the entire mass of air rather than just the flow rate. Because of the MAF’s important role, it should be attended to regularly, just as you would an air filter. It is important to measure air so the ECU can calculate the correct amount of fuel to inject into the combustion chamber to achieve the optimum air/fuel ratio.
