The engine can never work better than its MAFs.

. If the Mass Air Flow MAF Learned Status will not set to Learned after performing the procedure several times check for the following. Youll test this GM MAF sensor with a multimeter that can read Hertz Hz frequency. MAF sensor and air cleaner fouling.

The MAFs are vital to the proper function of the S62 engine. Here is a video on how you can test your MAF Sensor using a basic 5 Multimeter. A bad mass air flow sensor will usually trigger a check engine light.

As a car owner the condition. This is because the ECU will detect an out of range value coming from the MAF sensor and the check engine light is its way of letting you know that something is wrong. Ensure the Mass Air Flow MAF Learned Status reads Learned.
