Can sensor cause overheating?
Overheating engine The coolant temperature sensor can also fail in a manner that causes it to send a permanently hot signal. This can cause the computer to incorrectly compensate for a lean signal, which can result in overheating, and even misfires or engine ping.
Why is the temperature gauge pinned hot on my Honda?
Cut repair costs, not quality. Since you are experiencing no overheating problems the most likely cause is that the engine coolant temperature sending unit is faulty. This sends a signal directly to the dashboard gauge. There is another coolant temperature sensor close by which sends a signal to the ECU to help in engine management.
What should I do if my Honda Accord overheats?
Repair guides and support for the 5th generation Honda Accord coupe, sedan, and wagon. when starting the car the temp. gauge jumps to red hot ….I’ve been driving the car for 15 minutes max. one way thinking that the car may overheat but so far the car seems normal at these short distances.

What should the temperature gauge be on a hot engine?
With a hot engine it should measure 30-50 Ohms. If you measure around this value (or definitely not near 140 Ohms) with a cold engine then the unit is faulty and needs to be replaced. A quick test is to disconnect the lead from the sending unit, turn on the ignition and observe the temp. gauge.
How to test the temperature on a Honda?
Not quite certain if my figures are correct , but to test the sending unit, disconnect the single wire black connector and using a DMM (Digital Multimeter – Ohmmeter function) measure the resistance between the sending unit terminal and earth (or ground – the engine block will be earthed).

What happens when the temp gauge is on Hot?
When the temp gauge is on hot and I rev the engine, temp gauge needle goes down a little bit. Fan switches on on Hot reading, then turns off when the needle goes down a bit, still the engine is not smoking nor does it feel really hot. It’s just a normal temperature as far as I can tell.
