Code P0223 KIA Description

The P0223 diagnostic trouble code (DTC) for KIA vehicles refers to an issue with the Throttle Position Sensor (TPS) or Pedal Position Sensor/Switch 'B' Circuit, indicating a high input signal. The TPS is a crucial component that monitors the position of the throttle valve and sends this information to the engine control module (ECM) to adjust fuel delivery and ignition timing accordingly. When the ECM detects a high input signal from the TPS or pedal position sensor, it signifies that the voltage levels are outside the normal operating range, potentially leading to incorrect fuel and air mixture, affecting engine performance.

Cost to Fix P0223 KIA

The typical repair costs for addressing a P0223 code in a KIA vehicle can range from $100 to $300, including parts and labor. However, it's important to note that specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type.

To obtain a more accurate estimate, it's advisable to inquire about local rates before proceeding with the repair.

When is the Code Detected?

An excessively high voltage from the Throttle Position Sensor (TPS) is sent to Engine Control Module (ECM).
