Hello @Chris_top_he_r
You are actually looking at a BI technologies resistor array and should be rated at 47K ohms. Since you can’t measure ohms while installed I think the low reading is likely coming from the circuit and not the resistor.
Here is a copy of the datasheet for the L81S473

Looking at the datasheet it seems like 4608X-1-473LF-ND may be a good option for you to look at.
