Question about Honda Accord
There are only a couple things you can check. First, I would make sure the gauge is reading properly by checking the fluid temperature manually. Newer model cars have temperature sensors that can malfunction but they will usually set your check engine light off it that is the case. Check your radiator fluid. While the engine is cold!! See if it looks dirty. Rub it between your fingers and see how viscous it feels. Make sure the radiator is full. You may just need to get your radiator flushed. A lack of flow will cause an overheating condition. When your back in motion the engine has more pressure to circulate the fluid. When the car is moving there is airflow that also aids in the cooling process as well. Other than that you have a thermostat which could be sticking and causing it to overheat. Or the water pump is bad. A flush and fill and replacing the thermostat are fairly cheap and usually a lot easier to do than replacing the water pump. Especially on a Honda. Usually you will hear a squealing noise if your water pump is going out and there is, I think it is called a weep hole on the pump itself that will start to leak when the pump is going bad.

sounds like your low on coolant or you have air in the cooling system
water is needed for the sensor to show a true value and if your low or have air you sensor will at times because of the thermostat opening
go up and down. hope that got it

hi from uk from your symptoms of what happened re temp guage risen suddenly it would indicate the temp sender unit on the engine has blown ie is earthing to engine via its screwthreaded body this is just a matter of replacing with a new sender unit hope this helps

check the thermostat, the thermostat regulates water flow through your engine to cool it down sometimes they get stuck open or closed, remove it and put it through a simple test
grab a cup of cold water and a glass of hot water drop it in one then the other, you should be able to see if it opens and closes

Firstly - DO NOT run engine, when guage reads hot, as this will cause costly damage to head gasket & alloy engine head.
The fact that guage takes 1min to read HOT, would confirm the guage IS working properly.
So, other components which are likely to cause hot readings (in this order) are:
- lack of coolant (or leakage somewhere): is there sufficient green coolant at the correct level? Top up mixture to correct level. Repair any leaks.
- collapsed radiator hose: when engine is cold, start engine, then quickly watch both upper & lower radiator hoses to see if either begins to flex inwards (collapse). Replace if either hose is collapsed.
- bad/incorrect thermostat rating : when replacing thermostats, you must ensure it is of the SAME temp rating (they all differ).
- Incorrect Temp sensor rating: the ratings of this sensor must be within manufacturer's spec's.
- bad waterpump: the engine relies on the waterpump to distribute the coolant throughout the entire system. If waterpump is faulty, coolant will not flow quick enough, causing overheating.
If you still believe all of the above components are OK, then have your cooling system "pressure tested". This test should be done, before looking further at other electrical components.
