For whatever reason, your last comment about checking the 5V is not in the thread. I have and he also have removed the sensor. I also have 2 additional sensors. All have been checked with a multimeter and tested in hot and cold water. If I take a volt meter from either wire to ground, neither will give me 5 volts.

Dean, This is the plug I can't separate. I'm trying to test continuity between the sensor and this point first. I pulled the glovebox and looked at the BCM, that is no bueno for me.

Sorry to bother, I can't separate the plug. Found the Red release on the bottom side, but nothing I do works. Looks like a grey disk with a lever on the bottom side, but it's not moving either.

Thanks, I'll get on this this weekend.

So this connector is basically behind the headlight assembly, is that correct and in the other photo the actual BCM appears to be inside the car behind the glovebox?

2012 Journey. Temp display is -40. Sensor has been changed. Code is P0070. Mechanic said it appears to be a broken wire. Can't get 5 volts at the sensor. Looking for a wiring diagram so I can try and chase down the broken wire. I know the sensor harness goes behind the driver side headlight area, but not having any luck trying to chase it from there. Thanks. If this is the wrong subforum, feel free to move it.
