Below is video tutorial about a noise of a non-inverting operational amplifier circuit. On this video, we are explained about how to calculate the noise of a non inverting amplifier. What we have to do first is ground all the voltage sources. Because now all voltage sources is grounded, so the noise of non inverting configuration is exactly the same […]

This is a video of the engine coolant temperature (ECT) sensor. This video explains how the ECT sensor works. As the temperature goes up, the voltage goes down. Only two terminals are used, the ECM ground and the 5V reference terminal. The ECM ground is connected to the pin number 5 and the 5V reference coming from the ECM/PCM. Here […]

This video tutorial is about the hall effect WSS sensor. This video describes about how the hall effect sensor work. The wheel speed sensor uses the WSS family. Hall effect sensor are three wire sensors with the reference voltage, ground and the signal terminal. The reference voltage can be 5V,7V,8V or 12V. The reference voltage is supplied by the ABS […]

This is a EGR valve temperature sensor video. This video describe how the EGR valve temperature sensor works. The EGR gasses temperature sensor works like the coolant temperature sensor. The sensor uses the thermistor that has negative temperature Coefficient. That means the resistance decreases with increasing temperature. Here is the tutorial video: The operation of the EGR temperature sensor is […]

Below is video tutorial about automotive ignition coil. The coil is composed of primary and secondary circuit. The primary circuit is consist of two terminals. It’s connected to the steady 12 volts battery and ignition module or ECM. The secondary circuit is connected to the spark and carry a high voltage. The ECM module will always looks for returning voltages […]

This is a intake air temperature (IAT) sensor video. This video shows how the IAT sensor works. This sensor has two terminal, the ground terminal and reference voltage terminal. The ground is connected to the pin 5 of OBD-2 and the 5V refence signal is supplied by ECM. This sensor is maybe located in intake air deck. Here is the […]

Below is video tutorial about O2 or Oxygen sensor heater. On the Oxygen sensor, there are two wire with the same color. One color for O2 heater (+) and the other is O2 Heater (-). Oxygen sensor heater will always controlled by ECM but the control circuit will very depend on the manufacturer. There are 3 ways of the ECM […]
