How does the coolant temp sensor work on a Honda?
3. Disconnected the 2-pin wire harness for the ECT sensor and measured the resistance between both pins while the engine is cold. Measured the ambient temperature in my location and matched the resistance against this temperature through the chart along the specification path (specs).
Where is the ECT sensor on a Honda Civic?
Your Honda Civic’s engine coolant temperature (ECT) sensor is located in the front right section of your engine block.
What to do if your coolant temperature sensor is bad?
Connect the digital multi-meter to the coolant temperature sensor by connecting the red probe to the terminal end of the coolant temperature sensor and the black probe to the solid grounding. Note the readings. Start the engine and let it run for a couple of minutes at least. Note the readings initially while the engine is cool.
What’s the coolant temp on a Honda Accord?
The ECT sensors were off the charts indicating false readings that the engine was cold with the warmest reporting only 30 degrees celsius.
What are the symptoms of a bad coolant sensor?
Common symptoms of a bad engine coolant sensors are overheating, hard starting conditions, poor idle, check engine light ON and the electric fans do not work properly. The easiest way is to read the trouble code memory and check the value from the sensor, to make sure it’s a possible value.
What does a bad coolant sensor do?
A failing coolant temperature sensor will prevent a vehicle’s engine from entering a closed loop. This will cause the vehicle to run rich meaning the engine’s fuel mixture will have a higher percentage of fuel to air which will result in diminished fuel economy.
Where is the engine temperature sensor located?
Engine Coolant Temperature sensor is primarily located in the coolant passage of the liquid cooled engine; typically near the thermostat valve. The position of the engine temperature sensor. The engine temperature sensor connects either to the temperature gauge or to the temperature indicator in the dashboard.
What is a coolant temperature switch?
The coolant temperature switch, also called the coolant temperature sensor, is a switch that reads the engine coolant temperature and sends a signal to the engine control module, or ECM, to control other functions of engine operation such as the air-fuel ratio.
What are the symptoms of a bad coolant temperature sensor?
Hence, it is advised to have your car inspected right away to avoid any serious problems. Here is a more detailed list of the common symptoms of a bad coolant temperature sensor. One of the first symptoms you will notice is that the check engine light will activate.
What should coolant temp be when engine is hot?
With a good OBD2 code reader, you can also check the live data and the parameters of the CTS sensor. Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm.

Why is my oil temp sensor not working?
1) my oil temp sensor is bad or 2)I’ve never had the engine hot enough to trigger the fan to come on. I’ve only ridden about 15 minutes at a time so far and on.y about 10 times. Thanks for your help.
