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.

What causes a Honda Civic to run hot?

Your Honda Civic’s engine is designed to heat up to an operating temperature as quickly as possible. When the temperature is reached, coolant is allowed to flow into the engine block to keep the temperature constant. Low Coolant A lack of coolant will make the vehicle overheat.

Why does the temperature gauge on my Car Go Red?

Wondering what else can check for, seems this coolant temp sensor is at the end of the line of things.

What makes the temp gauge jump on a Honda?

Both of these will lead to excessive coolant overflow due to lack of circulation causing hot spots to develop where the coolant is boiling and expanding to push coolant out of the system. This also creates air pockets which can make the temp gauge quickly jump or fall.

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 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.
