Resistance Inspection

WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect MAF/IAT sensor.

Measure the resistance between the MAF/IAT sensor terminals D and E using an ohmmeter.

If not as specified, replace the MAF/IAT sensor. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L5] .)
