Why is the temperature gauge on my Honda Civic not working?
If there aren’t any clear wiring issues, test the wiring coming from the ECT sending unit (see Figure 3) with a multimeter. A warmed up engine should provide a resistance of about 38 ohms. If there’s no reading car is turned on, but a reading when the car is turned off, the gauge is likely the culprit.
Why does my temperature gauge keep going up and down?
One common cause of a temperature gauge that malfunctions is the thermostat. Sometimes the thermostat gets stuck open, which can cause the temperature gauge to “warm up” slowly, never move back down to operating temperature range, or fluctuate randomly. If the thermostat is not stuck open, it may simply need to be replaced.
Is it normal for the temp.gauge to go red hot?
Yes, coolant level is fine! The temp. gauge goes to red hot or pinned as soon as I start the car cold. And…after approx. 15 min. driving locally, the engine doesn’t seem to be overheated. so I’m assuming that the thermostat is working fine. I’m just afraid to drive it longer or farther when the temp. gauge says red hot.
What are the warning lights on a Honda?
The following are warning lights and indicators found in vehicles built by Honda. Click a link to learn more about each one. They are roughly ordered by importance, which tends to be by color (red, amber, yellow, orange, green, blue, gray).
Why does the temperature gauge on my Honda Civic still read Cold?
On the other hand, if the gauge still reads higher then cold when disconnecting the wire, replace the gauge. Check the temperature gauge fuse if you disconnected the wire at the sending unit (step 2), but the gauge failed to indicate Hot after grounding the wire (step 3).
What should I do if my Honda Civic overheats?
Check your coolant level and keep an eye on your temperature gauge. A car will run fine with an overheating engine right up to the point when the engine seizes. My research suggests that the 2012 Civic is not equipped with a temperature gauge, so that advice may not be useful. – Nate Eldredge Feb 3 ’15 at 4:55 Substitute “gauge” for “light”.

Why is the back of my Honda Accord over heating?
If so, its ok, the next main problem would be the radiator clogged, not allowing coolant to circulate from upper hose thru radiator to lower hose and back to engine. (so lower hose is cooler to the touch) . If both hoses are “HOT” then I would check the coolant Fans , mounted on the back of the radiator.
Why does my car temperature gauge read Cold?
If it reads ~30-50 Ohms or even s/c (short circuit) when cold then the sensor is faulty. You can also check that there is no visible connection between the brass body of the sensor and its’ silver connector tag, due to a manufacturing defect From your picture there is an insulator (brown ring) there. Use a magnifying glass if you want to.
When does the temp gauge needle go up or down?
Currently has 204,000 kilometres (127,000 miles) When the car is on a stop and idling, the temp gauge needle goes up steadily, and when the car is running, the gauge goes back to normal just as fast. When the temp gauge is on hot and I rev the engine, temp gauge needle goes down a little bit.

Why is my thermostat reading up and down?
A contaminated coolant system will cause inconsistent readings and requires a full bleed of the system to repair. If you have air or something else in the lines, your gauge will probably be reading up and down as it passes through or stay cold if air bubbles get stuck on the sensor itself. A broken thermostat will throw your temperature gauge off.
What to do if your coolant gauge is not working?
Using your coolant temperature gauge as an example, the diagnostic procedure involves locating and disconnecting the sending unit. With the ignition on, the gauge should register cold. If you connect the sending unit wire to ground, the gauge should switch to read hot.
How can I tell if my coolant temperature sensor is bad?
