In this video, we're diving deep into the world of Intake Air Temperature (IAT) sensors, focusing on their function, symptoms of failure, related OBD-II codes, and common causes. We'll also explore other issues that can cause similar symptoms to a bad IAT sensor.

Here's what we'll cover:

🚗 Introduction to Intake Air Temperature (IAT) Sensors:

Learn about the function of the IAT sensor and its role in helping the engine control unit (ECU) adjust the air-fuel mixture for optimal combustion and performance.
🔍 Common Symptoms of a Bad IAT Sensor:

🔧 Related OBD-II Codes:

Explore common OBD-II trouble codes associated with a bad IAT sensor, such as P0112 (Intake Air Temperature Sensor 1 Circuit Low Input) and P0113 (Intake Air Temperature Sensor 1 Circuit High Input).

🛠️ Causes of a Bad IAT Sensor:

Understand common causes of IAT sensor failure, including exposure to extreme temperatures, contamination from oil or coolant, and natural wear over time.
💡 Other Issues Causing Similar Symptoms:

Discover other potential causes of symptoms similar to a bad IAT sensor, such as problems with the mass airflow (MAF) sensor, manifold air pressure (MAP) sensor, or Faulty Fuel Injector.
