My truck is throwing code p0103 maf hight input. Already got a new sensor and tried to trace the wires but it's hard to do. Does anyone know any way to check the maf system

 

You cleaned it already or no?

How does the new MAF come? Does it have the connector and everything? I've never seen a new one but assumed it was just the complete piece by the sensor and you just plugged her in rather than splicing wires

 

It is the whole sensor. I found the problem there was antifreeze in the main plug where the engine wiring harness plugs into the PCM. I just put a new motor in it and had a little accident when putting the antifreeze in that plug must not have been connected yet and got wet
