In this video we explain each car engine sensor. For each sensor we explain what it does, how it does it, where the sensor is located and what happens if the sensor breaks. There are also OBD2 error codes for all sensors. Things like P0335, P0118, P0131, P0340, P0300, P0102, P0113.

So the next time you have a problem with one of your sensors, you'll know what's happening, why it's happening, where the sensor is, and what will happen if you don't fix it.

To make the video simple and logical, I grouped the sensor into 5 categories.

1. Position sensors (crankshaft position sensor, camshaft position sensor, throttle position sensor)
2. Air flow sensors (mass air flow sensor MAF, vane air flow meter)
3. Pressure sensors (MAP or manifold absolute pressure sensor, oil pressure sensor, fuel pressure sensor)
4. Temperature sensors (IAT or intake air temperature sensor, coolant temperature sensor, fuel temperature sensor, oil temperature sensor)
5. Air fuel ratios, emissions and others (oxygen 02 sensor both broadband and narrowband, EGT or exhaust gas temperature sensor, nitrogen oxide or nox sensor for SCR selective catalyst reduction and the knock sensor)

We will see how each sensor communicated with the ECU and how each sensor is a piece of the puzzle. When they all work together correctly, the ECU sees the big picture and manages engine operation accurately and efficiently. For example, the crankshaft position sensor tells the ECU where the piston is located, so the ECU knows WHEN to inject fuel. Airflow sensors such as the mass airflow sensor or the map sensor tell the ECU how much air is coming into the engine, so the ECU knows HOW MUCH fuel to inject. The throttle position sensor and intake air temperature sensor tell the ECU what load is being applied to the engine and what the intake air temperature is, further improving injection accuracy.

The final stream of information required for injection accuracy comes from the fuel pressure sensor, which allows the ECU to calculate exactly how long it needs to hold the injectors open to deliver the precise amount of fuel needed.

In case something goes wrong, we have life-saving sensors such as the knock or oil pressure sensors. The knock sensor listens for knock or abnormal combustion and if it detects it, it alerts the ECU and within milliseconds the ECU retards ignition timing and/or adds fuel to prevent knock from occurring again. The oil pressure and oil temperature sensors ensure that the engine oil, the lifeblood of the engine, remains within functional parameters. As soon as the ECU deviates even slightly outside the expected values, it can protect the engine and warn the driver.

All in all, modern cars are a moving world of information where a multitude of sensors quickly deliver endless amounts of data that is interpreted at lightning speed by the ECU, where it triggers a sea of ​​different actions that keep you moving smoothly and safely on the road. All this while maintaining efficiency and minimizing emissions.
