Code P1225 2009 Nissan Sentra Description
The P1225 diagnostic trouble code for a 2009 Nissan Sentra indicates a Closed Throttle Position Learning Performance Problem. This code is related to the throttle position sensor (TPS) and the throttle body. The throttle position sensor is responsible for monitoring the position of the throttle valve, which regulates the amount of air entering the engine. The closed throttle position learning process is a procedure that the engine control module (ECM) uses to learn the fully closed position of the throttle valve. If the ECM detects that the closed throttle position learning is not performing as expected, it will trigger the P1225 code.
