[4th Gen : 01-07]: Ambient Air Temp Sensor harness replacement, where does it connect to the PCM?
2005 3.3l Grand Caravan S
Could use some help with this, I have a p0073 code. I purchased a new sensor because the mounting bracket snapped off the old one, but the wires are visibly corroded and growing some blue fuzz. I can chase the wires near the driver's headlight, but at that point it all seems to join the main wiring harness.
Where do the wires for the Ambient Air Temp Sensor actually end up? I figured it would be easiest to just run new wires.
I have been looking at this schematic, which is for a 2004, but its the closest I could find.

Is the wire part of the fuel injector harness? If is does follow the harness and see if it going to the rear cylinder head. That area has be a problem of melting wires. I believe 2005 was the last year that harness was mounted to the rear cylinder head. If you do find the wires melted, there use to be a harness kit. And you may have to replace the PCM because of the wires shorting.
