What does it mean when the temperature gauge doesn’t move?

Why Is My Temperature Gauge Not Working? You can have broken wires leading from the gauge itself to the sensor or wires from the sensor to the engine control unit. It’s potential that any wire along the path could have come loose, corroded, or been somehow broken that would cause your temperature gauge to stop working.

What does it mean when your temperature gauge stays on cold?

Reasons the Temperature Gauge Reads Cold If the temperature gauge still reads cold after the engine has warmed up, the gauge may simply be broken. With the thermostat stuck open, the engine can be overcooled, causing a low temperature reading. If this is the case, the thermostat may need to be replaced.

Is there a sensor for the temperature gauge?

The temperature gauge utilizes a sensor, located near or in the thermostat housing, to send an electrical signal through the vehicle’s internal computer corresponding to the specific coolant temperature, giving the gauge on your dashboard an accurate reading of the temperature.
