Most frequently-reported cause I have seen recently on this Forum is cracks/ breaks in the hoses related to the PCV and Oil Separator, allowing "un-metered" air (air that did NOT pass through the MAF) to be sucked into the engine. The voltage supply to the MAF could be an issue, or any wiring or connector fault between the MAF and the DME (loose/ corroded/ damaged pins/sockets in at the connector, damaged wiring, etc.) could also cause it.

Basically, that signal is "out-of-range," completely lacking, too high or low voltage, etc., or the signal does NOT suggest measurement of the amount of air that should pass the MAF at a certain engine RPM.Ī faulty sensor COULD be the cause of such codes BUT, so could a leak in the ducts between the MAF and the intake take manifold, or even manifold gasket leaks.

The two FC you list: 2D06 & 2D0F, both have some relation to the SIGNAL from the MAF as received by the DME. Fault Codes should NOT be viewed as identifying WHAT COMPONENT to Remove & Replace.
