Cómo Diagnosticar CUALQUIER Sensor de Temperatura (Termistor) desde Cero

   • Thermistor Como Diagnosticar Sensor De Amb...   Want to learn automotive electronics but confused by sensors? In this video, I'll teach you, step by step and in the simplest way, how to diagnose any engine temperature sensor (thermistor) using your scan tool and a basic multimeter. What you'll learn in this beginner's lesson: The Mirror Test: How to compare the engine temperature sensor with the ambient temperature sensor when the engine is cold to see if they are calibrated. Disconnection Test: What happens on the scan tool screen when you disconnect the sensor (the famous -40°C trick) and why the computer reacts this way. Multimeter Measurement: How to measure the 5V reference voltage sent by the computer and how it changes when the sensor is working. This method applies to water, air, oil, and ambient temperature sensors. Master this test and you'll be able to diagnose half of a car's sensors!
