if 4,6L Color is usually yellow or red egr - under manifold in rear O2 - rear back in axhaust manifold
The signal wire should be Tan. You should have a Yellow, Black, and Tan Wire. The Yellow being you MAF Sensor Signal. The Black being a Low reference voltage. Then your Tan your IAT sensor signal.
not sure the exact location of the wire in the harness, but i can tell you that the speed sensor has 2 wire leads, that run directly to the PCM. they are in ports 20 and 21 on the PCM wire connector. Pin 20 is for speed sensor low signal and is Light green and black in color. Pin 21 is for speed sensor high signal and is purple and white in color
you might try www.haynes.com, these are the folks that have all the manuals for wiring etc.
The black wires are the heater wires, the white wire is the signal wire and the green is the ground wire.
It is used to separate the color burst signal from the color signal.
Black for signal, Gray for ground, 2white's for heat
I believe it is the black wire coming from stock o2 sensor. I have tested this wire with votmeter and have seen voltage fluctuation from 200 mv - 900mv. I think this is correct.
right by the oil filter you should see a gold color one wire sensor.
What color wires at the maf sensor belong to the iat sensor?
yes
The color of the sensor is black and is location is behind the trasmision
code113 for iat sensor
