Duster temp gauge problems
Start by checking the sensor resistance. Here are the standard test resistors for checking gauges: IE the sensor should kinda match these at cold and operating.
You can tell if the sender is grounding by checking between the brass shell and the intake. Do NOT overtighten these. You can ruin them by doing so.
It is possible that even though the gauge pegs when grounded, it has a problem over the operating range, like, bent needle dragging on the gauge face, etc
