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...
How To Test Coolant Temp Sensor The tip of the ECT sensor needs to be immersedin the engine’s coolant. In the process, the air pocketsor low coolant levelin the cooling system can manipulate the sensor’s signals, giving the wrong information. When dealing with any problemrelated to coolan...
Lift the hood and locatethe coolant temperature sensor. Make sure the engine is cold before removing the sensor. Unplug the sensor electrical connector. Step 2 Remove the sensor using the appropriate deep-well socket. Very little antifreeze will be lost due to the location of the sensor. Step ...
A CPU cooler keeps your chip cool by pulling heat from the CPU toward the baseplate/heat pipes. The heat transitions from gas to liquid via the condenser and cools down through the heatsink fins and fan. This “cooled down liquid,” or coolant, makes its way back down through the evapora...
Geothermal coolinguses the near-constant temperature of the Earth below surface level to provide cooling. It's a centuries-old idea, once used to keep food cold, adapted to our modern era. In data centers, geothermal cooling uses a closed-loop pipe system with water or another coola...
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 ...
The manifold absolute pressure sensor, or MAP sensor, is used to measure the amount of air flowing through the intake system and into the engine. The sensor sends airflow rate data to the Honda engine control unit, or ECU, which can then adjust the air-t
1. The number one reason for an air conditioner to stop working is lack of refrigerant. When this part liquid, part gas runs low the AC system is equipped with a pressure sensor that will shut the system down to protect the compressor. To check the refrigerant level, simply attach a ...
Using pliars, twist the valve counter clockwise and have a bucket ready to catch the coolant coming from the spout. Now disconnect 4 sensor plugs. The Intake Air Temp Sensor in the lid, the MAF sensor plug, and the two plugs that go into the drivers side of the throttle body. Pop ...
even with heavy burnin of the new coolants, the fan barely spins up, the temperature of the cpu dropped noticably, as well as the gpu’s temps IML Tech May 16, 2010| Martijn van der Klip, i removed all the cooling paste from the cpu, and the cooling PAD from the gpu (no paste?
