Fuel Cut-off Control-2005-2006 Models

During deceleration with the throttle valve closed, current to the injectors is cut off to improve fuel economy at speeds over 980 RPM (1,150 RPM)^*2 . Fuel cut-off action also occurs when engine speed exceeds 6,500 RPM (7,800 RPM)^*2 , regardless of the position of the throttle valve, to protect the engine from over-revving. When the vehicle is stopped, the ECM/PCM cuts the fuel at engine speeds over 3,500 RPM.
