The other day I started up my truck and it threw this code. P0103 mass or volume air flow circuit high input. I cleared the code and it comes right back when I start the truck up. I checked the connections and cleaned the maf sensor. Everything looks good and the code is still there. Any ideas on how to fix it? I am getting tried of seeing reduced engine power come up on the dash.

MAF Mass or volume air flow circuit high input Restriction, water intrusion, signal short to voltage, return circuit open, faulty sensor, faulty PCM.

It could be a broken sense element, test the MAF you need a frequency scale on a DVM multi-meter to check it.If you have a K&N on your truck get rid of it.
