Fuel Cutoff Control

WARNING: This page is about a different car, the 2013 Honda Fit, 2012 Honda Fit, 2011 Honda Fit, 2010 Honda Fit, and 2009 Honda Fit. 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 engine speeds over 850 rpm (A/T) (M/T: 907 rpm). Fuel cutoff also occurs when the engine speed exceeds 7, 000 rpm, 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 5, 000 rpm (A/T) (M/T: 4, 800 rpm). On a cold engine, fuel cut occurs at a lower engine speed.
