The video describes how temperature sensors (NTC thermistors) work, which is applicable to effectively diagnose ANY sensor of this type such as: -ECT -IAT -OTS -EGTs -FTS -Ambient temperature sensor (HVAC) -BTS (hybrid/electric battery) -Electric motor temperature -Inverter temperature (hybrid/electric) -among others. Although the sensor resistance and signal voltage will obviously not be the same for each make and model of vehicle, THE BEHAVIOR OF THE VOLTAGE DIVISOR IS and therefore allows an UNDERSTANDING of the sensor that will increase your automotive diagnostic skills. The behavior of the voltage divider circuit is analyzed with simple mathematical calculations that demonstrate that when the sensor resistance decreases, the signal voltage to the computer must also decrease.
