Coolant Level too low (or sensor went bad)
or
Engine Compartment Temp too high / engine compartment fan failure
It means the engine may be overheating.

The Porsche Cayman S typically takes around 10 to 15 minutes of driving under normal conditions to reach its optimal oil temperature. This timeframe can vary based on factors such as ambient temperature, driving style, and engine load. It's important to allow the engine to warm up gradually to ensure proper lubrication and performance. Monitoring the oil temperature gauge can help determine when the engine is fully warmed up.
Your engine coolant temperature gauge has a sensor ( there is also a engine coolant temperature sensor that is used for the computer / PCM )
A signal from the temperature sensor on the engine.
The temperature gauge on a 2002 Ford 4.0 SOHC V6 is controlled primarily by the engine coolant temperature (ECT) sensor. This sensor monitors the temperature of the engine coolant and sends corresponding signals to the engine control module (ECM). The ECM processes this information and relays it to the temperature gauge on the dashboard, allowing the driver to monitor engine temperature. Additionally, the gauge's behavior is influenced by the vehicle's electrical system and the gauge's calibration.
Switch the ignition off and start the car again.The light will then stop flashing.
The average aircraft will have temperature gauges for the following: Outside air temperature, Engine air inlet temperature, Engine exhaust temperature, cabin temperature, and that's just on a small aircraft. So which temperature gauge do you mean?
The temperature gauge in an Alfa Romeo, like in most vehicles, operates by monitoring the engine coolant temperature. It uses a temperature sensor located near the engine or in the coolant passage, which detects the coolant's temperature as it circulates. The sensor sends this information to the gauge on the dashboard, where it displays the temperature level, helping the driver monitor the engine's operating condition. If the engine overheats, the gauge will indicate a high temperature, prompting the driver to take action to prevent damage.
The three most important gauges or indicators to be aware of are the fuel gauge, engine temperature gauge, and oil pressure gauge. The fuel gauge informs you of how much fuel you have left, preventing unexpected runs out of gas. The engine temperature gauge helps monitor the engine's operating temperature, alerting you to overheating issues. Lastly, the oil pressure gauge indicates whether the engine is receiving adequate oil flow, which is crucial for lubrication and preventing engine damage.
No - the gauge reports 'real-time' the engine temperature. If it is wrong, there is a problem with the sending unit on the engine. This is a pretty easy fix...
i just put in a new radiator and now temperature gauge reads high but their are no leaks
