Coolant sensors have two wires (input and return). A 5-volt reference voltage signal is sent from the PCM to the sensor. The amount of resistance in the sensor reduces the voltage signal that then returns to the PCM. The PCM then calculates coolant temperature based on the voltage value of...
Do you know how to test radiator fan with multimeter? There is a sensor on the bottom passenger side of the radiator. It does the job of taking notes of coolant temperature. It sends signals to the radiator fan to turn on when the temperature crosses 172°F. The fan should also turn ...
Another design issue is how to determine whether a larger number of branchings (i.e., a “more dendritic” structure) leads to a performance improvement, and how to quantify the correlation between the number of branches and the DSHE performance. Finally, one must investigate whether the ...
If the coolant contains silicates (conventional green antifreeze), it can also foul the oxygen sensor and catalytic converter. If enough coolant leaks into the cylinder (as when the engine is sitting overnight), it may even hydro-lock the engine and prevent it from cranking when you try to ...
This test is also good for checking ablown head gasket, once all of the spark plugs have been removed, coolant will pour from the spark plug holes indicating the failure. If you cannot get the system to hold pressure chances are coolant is pouring out of a leak somewhere, or the pressure...
Learn about RTD sensors (Resistance Thermometer Detectors), types of RTD sensors, how they work, and how to measure temperature with Dewesoft DAQ systems.
To detect thebad map sensor symptoms, it is highly recommended to get the vehicle check consistently through an emission test. If the test depicts a large amount of NO, hydrocarbon production alongside low CO2 and high levels of carbon monoxide through the tailpipe then, it indicates the issue...
Your temperature gauge, which measures the temperature of engine coolant, will alert you to a dangerous situation. There are a host of other warning lights designed to let you know about the status of the car. Though there have been some efforts to standardize these lights in all makes ...
2. Once the coolant has been drained down slightly, insert the test tube into the radiator filler neck, then add test fluid to the full line on the side of the tube. 3. Start the engine, while using the hand pump draw air inside the radiator into the tester, repeat this action about...
