Understanding the Intake Air Heater
The intake air heater is a component in your vehicle’s intake system that is designed to warm up the incoming air to help improve fuel efficiency. The heater is controlled by the engine control module (ECM) and is triggered by temperature sensors that are located in the intake system. When the ECM detects the incoming air temperature is too cold, it will activate the heater to help warm up the air.
