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, high RPM). Fuel-cut system will also deactivate injectors when engine speed exceeds 6800 RPM (Esteem, Sidekick 1.6L, Swift and X-90) or 6550 RPM (Sidekick 1.8L). This is done to prevent engine damage due to excessive engine speed. As engine speed drops to less than 6500 RPM (Esteem, Sidekick and X-90) or 6600 RPM (Swift), injection will once again occur.
