Code P0223 2004 Nissan Maxima Description

The P0223 code in a 2004 Nissan Maxima indicates a problem with the Throttle Position Sensor/Switch 2 Circuit, specifically a high input signal. The throttle position sensor (TPS) is a crucial component of the vehicle's fuel management system, as it helps regulate the amount of air entering the engine. The TPS communicates with the engine control module (ECM) to ensure the engine receives the correct amount of fuel based on the driver's input through the accelerator pedal.
