Why is the temperature gauge pinned hot on my Honda?
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.
Which is the most expensive type of temperature sensor?
While providing the greatest accuracy, RTDs also tend to be the most expensive of temperature sensors. 3. Thermocouple This temperature sensor type consists of two wires of different metals connected at two points. The varying voltage between these two points reflects proportional changes in temperature.
What should temperature sensor resistance be when cold?
The resistance of the sensor between the body of the sensor and the sensor connector tag should be ~140 Ohm when cold. (you can do this out of the engine) If it reads ~30-50 Ohms or even s/c (short circuit) when cold then the sensor is faulty.
What kind of temperature sensor is used in concrete?
The Encardio-rite Model ETT-10V vibrating wire temperature meter is used for the measurement of internal temperature in concrete structures or water. It has a resolution of better than 0.1°C and works similar to that of Thermocouple Temperature Sensors. It also has a high temperature range from -20 o to 80 o C.
What to do if your temperature gauge is pinned Hot?
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. If it registers ‘zero’ then most probably the sending unit is faulty.

How does the temperature gauge on a Honda work?
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. You shouldn’t get confused between the two as the one you want only has one wire and the other has two.
Why does the temperature gauge on my Car Go Red?
When disconnecting single wire coolant sensor, and starting car gauge on dash stays at zero. However, when replacing with new sensor, gauge on dash goes to full red at startup, very surprised by this. Wondering what else can check for, seems this coolant temp sensor is at the end of the line of things.
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.
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 should I do if my temp.gauge says zero?
A quick test is to disconnect the lead from the sending unit, turn on the ignition and observe the temp. gauge. If it registers ‘zero’ then most probably the sending unit is faulty.
