    How do you remove the MAF sensor? Posted by Customer
    A:
    To remove the MAF sensor, you can remove the air intake duct on V6 models and disconnect the electrical connector by depressing the release tab and detaching the connector. Then, loosen the hose clamp screws that secure the MAF sensor to the air filter housing and remove the sensor. Also, the installation is the reverse of the removal.
