Nissan Versa (N17): Normal operating condition

Nissan Versa 2nd generation (N17) Service Manual / Engine / Engine control system (EC) / Normal operating condition

Description

FUEL CUT CONTROL (AT NO LOAD AND HIGH ENGINE SPEED)

If the engine speed is above 2,400 rpm under no load (for example, the shift lever position is neutral and engine speed is over 2,400 rpm) fuel will be cut off after some time. The exact time when the fuel is cut off varies based on engine speed.

Fuel cut will be operated until the engine speed reaches 2,000 rpm, then fuel cut will be cancelled.

NOTE: This function is different from deceleration control listed under Multiport Fuel Injection (MFI) System, EC, "MULTIPORT FUEL INJECTION SYSTEM : System Description".
