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.

Why does my coolant temperature gauge read Cold?

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. If the gauge moves as expected, then you can suspect a bad sending unit.

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.

What does it mean when your temperature gauge says your car is too hot?

Temperature gauges are normally very reliable. An abnormal reading usually indicates a temperature-related problem in your engine, not a bad gauge. But it is possible for the gauge to malfunction.

What causes a steady cold reading on a car temp?
