Fuel Cut-off Control
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2005 Honda S2000, 2004 Honda S2000, 2003 Honda S2000, 2002 Honda S2000, and 2001 Honda S2000. However, it is still accessible from the selected car via links, so may be relevant.
During deceleration with the throttle valve closed, current to the injectors is cut off to improve fuel economy at speeds over 1,050 RPM.
Fuel cut-off action also occurs when engine speed exceeds 9,000 RPM, regardless of the position of the throttle valve, to protect the engine from over-revving.
