Fuel Cut Control Unit: Testing and Inspection

Fuel Cut-off Control

During deceleration with the throttle valve closed, current to the fuel injectors is cut off to improve fuel economy at engine 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 stopped, the PCM cuts the fuel at engine speeds over 5,000 rpm.
