Throttle alarm. How does warm air turn into cold air?

Throttle position sensor failure, engine computer failure, air intake system leakage or blockage, etc.

1. Throttle position sensor fault: Throttle position sensor is used to detect throttle opening. When a fault occurs, the engine computer will not be able to accurately determine the throttle position, thus affecting the normal operation of the heater.

2. Engine computer failure: The engine computer is the core component to control the engine. When it fails, it will lead to abnormal throttle control signal, thus affecting the normal operation of the heater.

3. Leakage or blockage of the air intake system: The air intake system is an important part of the engine. When the air intake system leaks or is blocked, the air intake of the engine will be insufficient or abnormal, which will affect the normal operation of the warm air.
