I hate to state the obvious but did you open the hood and check coolant level?

Every time a coolant reservoir is replaced, it takes some time for the level to settle down (air bubble).

Hey all .. MDK here. So, the other day I changed out my overflow bottle and now I got the prompt on the Driver's information module. Did tell you all how much I hate computers on cars? I had swapped out the sensor, all the hoses and the cap. I didn't even unplug it.. just popped out and popped it into the new one... very carefully. Put the $π|∆ all back together..re-fill.. check for leaks, started it up and bam ==°¥¥°{×{¥π={¶ CODE!! AHH! I know that the sensor is factory.. maybe by just disturbing it I might have damaged it in some way..... now what do I do! Any thoughts ??
Which car is this on? Its easy to damage those sensors if you tug on them when replacing the bottle, and they fail in a mode that triggers the low coolant warning (a good design)

As above, if for some reason we need to lift the coolant reservoir (sometimes along with the P/S reservoir for work at the timing belt, etc), just slightly pulling on the sensor cord can make it to fail - even if nothing looks broken. This is why I always unplug the sensor first, then lift the coolant tank. The connector is sandwiched between the ECM box and the wall. Same goes with ABS sensors, just a slight pull on the wire near the sensor and kaput

A used sensor from the junkyard should do the trick

Also check the float inside the reservoir, sometimes it may get stuck at the bottom

Thanks Oragex... that's probably what has happened. Even as careful as I was. The reservoir is full cold...I unplugged it and did a continuity test and the circuit seems to be open. I guess I need a new one. 16$ from IPD. I'm going to go plug in my VIDA and see what I can see... thanks guys... really appreciate you taking the time to read my post...

So I hooked up my VIDA and really didn't get a read out on the level sensor however..did get a read from the fuel pressure sensor... signal too high. So I guess I need to get that to from my friends @ IPD... RRRRR

Clear that code and monitor - there is no reason to replace parts based on codes if the car runs well.
