Fuel Cut Control

Fuel Cut-off Control
During deceleration with the throttle valve closed, current to the fuel injectors is cut off to improve fuel economy at speeds over 1,100 rpm.
Fuel cut-off action also occurs when engine speed exceeds 6,600 rpm, regardless of the position of the throttle valve, to protect the engine from over-revving. When the vehicle is stopping, then PCM cuts the fuel at engine speed over 5,000 rpm.
