Nissan Altima (L32) 2007-2012 Service Manual: Normal operating condition

Description

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

If the engine speed is above 1,400 rpm under no load (for example, the selector lever position is P or N and engine speed is over 1,400 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 1,000 rpm, then fuel cut will be cancelled.

NOTE: This function is different from deceleration control listed under Multiport Fuel Injection (MFI) System, EC-1065, "System Description".
