997.2 CEL issue with air flow
I've been trying multiple things to get rid of my CEL which remains a challenge. I changed the air filters from K&N oil metal filters to regular paper filters. All the literature I've read days the oil-based filters gum up the MAF so took them out. I then cleaned the maf with CRC fluid by spraying liberally. Let dry and reinstalled. The CEL came back on immediately. Here are the codes that I got on my Durametric enthusiast cable:
7910 air mass ahead of throttle valve idle no signal communication
9410 implausible mass air flow ahead of throttle valve. value below lower limit value
I then talked to my shop mechanic and he described needing to reprogramming the ECU and told me to redo exactly what I just did except also unplug the battery for 30 minutes . After doing so and reconnecting the battery cable, I found a PSM initialisation error that cleared itself after I drove the car. For a few minutes. Still one day later thr cel light came back on. I haven't had a chance to check the new codes but I am assuming that the code will be the same as before.
So now I am groping then Web for other ideas to try before I break down and buy a new $500 maf sensor. The cable for the sensor is partially melted Btw - about six inches from the housing. It seems to have touched something hot since it loops down from the housing. I am wondering if the partially melted cable may have something to do with it.
In any case, and ideas on where to check and what could be the issue? Thank you.
