gretsch64 Posted March 3, 2011 Report Share Posted March 3, 2011 Our 2003 Cadillac Deville has a trouble code reading of PO 101 which is mass or volume air flow circuit range performance. Is there any way I could remedy this myself or if not how much might this repair cost? Link to comment Share on other sites More sharing options...
cdgrinci Posted March 3, 2011 Report Share Posted March 3, 2011 You can try to clean the MAF sensor wire. Sometimes this will correct the problem. You can use intake cleaner, brake cleaner or they even make a mass air flow cleaner. Whatever cleaner you try has to clean without leaving any residue. If this doesn't correct the situation, you'll have to replace the sensor.
