EVERY ENGINE SENSOR EXPLAINED – MAF, MAP, IAT, TPS, 02, NOx, EGT – How it works, location, OBD2 code

AEM SS MAP sensors are used for precise measurement of various data in vehicles. AEM wideband, AEM IAT, AEM FLUID TEMP, and AEM EGT are all different types of sensors that play important roles in engine performance.

The video starts with an introduction followed by explanations of different car engine sensors such as the crankshaft position sensor, camshaft position sensor, throttle position sensor, Mass air flow sensor, Vane air flow meter, and more. Each sensor’s function, location, and potential issues are discussed, along with corresponding OBD2 error codes.

The sensors are categorized into groups such as position sensors, air flow sensors, pressure sensors, temperature sensors, and air-fuel ratios. Each sensor communicates with the Engine Control Unit (ECU) to ensure optimal engine performance, with examples given for how information from sensors influences fuel injection and overall engine operation.

In case of sensor malfunctions, certain sensors like knock or oil pressure sensors serve as safeguards to protect the engine from damage. These sensors can detect abnormal conditions and trigger actions from the ECU to prevent further issues.

The video highlights the importance of sensor integration in modern cars, where a network of sensors continuously provides data to the ECU for efficient and safe vehicle operation. The patrons of the video are also acknowledged at the end.
