Throttle is power. A vital vehicle function, without it functioning correctly, you will either travel too fast or not at all. Since the invention of the car, throttle systems haven’t evolved much. The core of a throttle body still revolves around a valve that lets air into the intake. The only change is the introduction of electromechanical actuators instead of old-school throttle cables.
Repairing these electromechanical systems can be difficult, which often means they have to be replaced when they fail. However, these same systems have made diagnostics easier, as they can be accessed and diagnosed through the engine computer.
The P0223 check engine light code is the diagnostic code triggered by an issue with the throttle position sensor. Here, you’ll find specialized information on how to diagnose each component, potential fixes, causes, and symptoms. So, let’s get into it!
