November 6, 200718 yr Hi Guys, I hope everyone is well. I am looking at my 1996 Outback Wagon, automatic, 2.5L. I just got an OBDII scan tool that is showing an MAF reading of zero. However, no trouble code is registering in the car's computer; i.e. my MIL/check engine light is off. There is not a lot of troubleshooting data in the Haynes manual: 4 to 7 grams/second under idle is the expected range. I would like to make sure the wiring is OK. I already checked for +12VDC on one of the pins. Would I get a trouble code if the wiring was not OK? Is there anything I could do to the sensor aside from beating it to get it working? Does it come apart? If it is bad, is my only choice to replace it? I read in one of the posts that someone replaced only a $55 "reed". I haven't seen that part online yet. There isn't terrible performance but I would like to know that I am getting optimal fuel mileage for my car. Any and all responses are appreciated. Take care.
November 7, 200718 yr I would suspect your scan tool is not reporting the value. If you were really getting a reading of zero I would imagine you would have a CEL/MIL.
