Code P1226 2012 Nissan Rogue Description

The P1226 code on a 2012 Nissan Rogue indicates a Closed Throttle Position Learning Performance Problem. This means that the engine control module (ECM) is not receiving the correct signals from the throttle position sensor (TPS) when the throttle is closed. The TPS is responsible for monitoring the position of the throttle valve and sending this information to the ECM to adjust fuel delivery and ignition timing accordingly. When the ECM detects that the closed throttle position learning is not performing as expected, it can lead to poor engine performance, decreased fuel efficiency, and potential drivability issues.
