EOT (engine oil temp) very low

Posting this for a friends truck...

I am scanning my EOT and ECT temps to see what they are before I do a coolant flush and switch to ELC. I am using a SCT dashscan and saw that my ECT temps are around 190-195 and that my EOT temps are reading around 50. I assumed that my eot sensor was bad so I installed a new motorcraft sensor today and I still have very low temps.

I checked the 6.0 bible and saw that the voltage (in) is suppose to be 5 volts. I have 5 volts with the plug disconnected but as soon as I plug it back in the voltage drops to 1.2 volts. What I need to know is what should I check for now? Is it possible the plug itself is bad? I have seen them for sale on Ebay and I assume that this is because they go bad. I also tried to push the terminals down on the plug just to make sure they are making contact. I tried to check the voltage coming out of the plug but it was not reading anything, and voltage in dropped to 1.2 when plugged back in.
Thanks in advance for the help.

Dashscan BAD!!! See if you can get your money back and get a ScanGuage II. The dashscan is reading EOT in Celsius.

Dont disagree wit ya but I have had a dashscan in my hands and thats what we found out. The dashscan was not set up to monitor oil temp correctly from SCT. ScanGuage II, need it, gotta have it, cant live without it

Dashscan doesnt read EOT properly regardless of celsius temps.
