You need to open up the splices and investigate for shorts/opens/ref voltage

Check the CTS's resistances and when continuity checks out on the wire, you should only have 2 splices when completed. If CTS and wire checks out-might be the gauge itself.

HTH Good Luck!

Suggested Repair

Open the splices and check for shorts, opens, and reference voltage. Verify coolant temperature sensor resistance and continuity, then repair the wiring so only two splices remain. If the sensor and wiring test good, the gauge itself may be faulty.

Conversation Summary

The owner of a 2001 Ford Explorer with a 5.0 reports a non-working temperature gauge and code P0125 after replacing the coolant temperature sensor. The connector wiring has been spliced in four places. The expert advises inspecting the splices for shorts, opens, and reference voltage, checking sensor resistance, limiting the completed repair to two splices, and considering the gauge if the sensor and wiring check out.
