Purchased 2010 Expedition 5.4 showing maf & air temp error codes, both look to be combined in the one sensor.
Wires on the harness have been cut and spliced back together right b4 the sensor connector so that's where I took my readings.
I have a good ground (green)
+5vdc (purple)
Everything else 0vdc
Would appreciate a good jumping off point to start rather than the roof..
Thanks
