SOLVED 'Mostly :-)"

Ok, I found the problem and resolved the issue. As I mentioned earlier I was able to clear the DTC check engine code, the one that was reporting the specific code of "B18C0" using my HyperTech programmer BUT still can't locate its meaning but then 10 minutes after clearing it the check engine light came back on so I just went ahead and scheduled an appointment with the Dealer to have it looked at, my apt was for 8:00am on Friday 01/15/2016. I wanted to give it one more shot myself before going to the dealer so using the programmer I read the code again assuming it was going to give me the same "B18C0" code again, BUT it didn't, this time it gave me two codes, they were "P0196" & "P0198" and those I was able to locate. From my research their definitions are below.

[P0196 - Engine Oil Temperature Sensor Range/Performance]

[P0198 - Engine Oil Temperature Sensor High]

This made more sense to me (kind of) because not too long ago I replaced my dash gauges with after market ones BUT I never touched the factory sensors, ie: Oil Temp Sensor, Oil Pressure Sensor because I used a sandwich adapter which has threaded holes in the adapter plate which fits between the engine block and the oil filter. However I guess when performing the work I must have bumped the factory sensor BUT that is a little strange because the check engine light didn't come on until a month after installing the new gauges but I must have touched it or it perhaps vibrated loose causing it to become disconnected (the pins internal to the plastic connector NOT the connector physically becoming disconnected from its mating connector) which I still find odd because any of you who have worked in this area know that the factory Oil Temp Sensor and Oil Pressure Sensor are clicked into place using a very strong connector and removing them takes a strong grip to depress the plastic release on the connector. After disconnecting it and reconnecting it the check engine light went away. I verified the pins inside the plastic connector were clean and free of any dirt or grime. Still not sure what that B18C0 code was but it hasn't returned but you know how we like to know what's up so I wish I was able to figure out what trip it and what it meant. Does anybody know how the Dealer would look up the DTC's engine codes? Meaning do they have a list of ALL codes and their definitions and is that a fairly easy task given you take your place in line? What I am asking is would it really be that hard for them to just look up that specific code and tell me what the text book meaning is without having to pay them for a formal visit and waste 2-4 hours? I find it aggravating when you can't just call in and ask them to look up a code, it is not like I was asking them to do any troubleshooting just what ever their computer says about that code so I could head in the right direction you know? but what ever...

Thanks again for those who chimed in, I appreciate it.....

PS: Am very happy with the gauges I will find the appropriate thread and post some pics, perhaps drop one pic here too. Will need to snap a couple of shots. A bit of a challenging DIY but it turned out good.

Here is what I had installed:
1) 60mm Depo Racing Water Temp Gauge (7 color) (Analog with needle with L.E.D warning indicator)
2) 60mm ProSport EVO series Oil Temperature (4 Color) (Digital with extra external Warning Lamp)
3) 60mm ProSport EVO series Oil Pressure (4 Color) (Digital with extra external Warning Lamp)
4) 60mm ProSport EVO series Voltage (4 Color)
