Fuel-Cut System

The fuel-cut system will stop fuel injection during deceleration to prevent excess fuel build-up during periods when oxygen is insufficient for combustion (i.e. closed throttle deceleration).

Fuel-cut system will also deactivate injectors when engine speed exceeds 7200 RPM (Sidekick), 7500 RPM (Swift DOHC) or 6800 RPM (Samurai and Swift SOHC). This is done to prevent engine damage due to excessive engine speed. As engine speed drops to less than 6800 RPM (Sidekick), 7460 RPM (Swift DOHC), 6500 (Samurai) or 6600 (Swift SOHC), injection will once again occur.
