1999 NISSAN PRIMERA Control

System DescriptionNCEC0444
Sensor Input Signal to ECMECM func-
tionActuator
Camshaft position sensor (REF) Engine speed
ECM Fuel pump relay
Ignition switch Start signal
The ECM activates the fuel pump for several seconds after the ignition switch is turned on to improve engine
startability. If the ECM receives a 180É signal from the camshaft position sensor, it knows that the engine is
rotating, and causes the pump to perform. If the 180É signal is not received when the ignition switch is on, the
engine stalls. The ECM stops pump operation and prevents battery discharging, thereby improving safety. The
ECM does not directly drive the fuel pump. It controls the ON/OFF fuel pump relay, which in turn controls the
fuel pump.
Condition Fuel pump operation
Ignition switch is turned to ON. Operates for 2 seconds
Engine running and cranking Operates
When engine is stopped Stops in 1.5 seconds
Except as shown aboveStops
Component DescriptionNCEC0501A turbine type design fuel pump is used in the fuel tank.
