1 Open the top and find the air intake system.

 2.  Slacken off the hose clamps that constrict the air filter to the air intake boot in front of the mass air flow (MAF) sensor/air mass meter.


Slacken the hose clamps that hold the mass air flow sensor (MAF) /air mass meter to the intake boot and to the engine. Do away with the mass air flow sensor/air mass meter for examination, cleaning or replacement.


Check the mass air flow sensor/air mass meter wires in a direct light source. Look for any dirt build up that would hinder the engine computer’s reading of the air flow. If washing (only) is needed – then use a spray (aerosol) cleaner selected/formulated for mass air flow meters. Use of any other type of cleaner may harm the sensor.


Clean the air intake hose – particularly on the intake side of the MAF sensor.


Put in the new or cleaned mass air flow (MAF) sensor/air mass meter unit. Constrict the sensor bolts.


Constrict all hose clamps and check the complete air intake system for leaks.
