on side has a red and a black the red has 12 v
the other side has 4 wires with the grey showing 4.5 v

 

1/2 the only ground from all 6 posts is on the 4 post side being grey w/ red stripe.

 

I believe we are going to need a scan tool that can provide the info we need to be sure the info is reliable.

 

I know I get confusing at times but here's where I'm at, I have a 2001 E250 w/V6,
Some time ago it started to lose power and idle a little rough. In OD it would actually seem to mis.
It is throwing P-102, P-112 and P-113. The air temp and air flow sensors I think must be both on one sensor as there are no other wires or connectors on the air tube to the TB but one, it has 2 posts and under in the same connector has 4 posts.
Of the 2 the red wire has 12v, the black w/grey is grounded.
Of the 4 post side the grey w/red stripe is grounded and the grey has 4.75v.
I can not find any vac leaks anywhere.
Any help would be great!

 

The codes 112 and 113 contradict one another.. I am trying to figure out how the same wire/circuit can have 2 different voltage readings.

One thing of which I am pretty sure of and that is NONE should have 12 volts to or from them. I suspect there is a short to power some place.

Is there any way you can trace the wire that shows 12 volts and see where it goes or comes from? It should not have 12 volts on it..

 

The wires go into a large bundle, but I will try and let you know, thanks

 

I'm really not lazy, but if the red wire on the 2 pin side (must have a short) has 12v which is wrong what if I cut the red one and shared the wire in the 4 pin side that has 4.75 v?
The bundle that the 6 wires go into is like the main harness that goes 2 directions, wrapped/ about 2" in diameter.
Or if you or someone knows where the other end of the 6 wires wind up, I could maybe start at that end.

 

I hear you,
Suppose we wait and see if Heiko can produce a diagram. Because We don't know where the wires go, it would not be a good idea to alter anything and we could wind up creating more problems than we presently have.
I will do some digging and I might have one, OK with you ?

 

I can wait, thank you!
