2004 NISSAN TERRANO turn signal

ACCELERATOR POSITION SWITCH
The accelerator position switch detects OFF-accelerator switch sig-
nal and Full-accelerator switch signal and sends these signals to
the ECM. The ECM will then determine engine idle conditions.
These signals are also used for diagnosing the accelerator position
sensor.

Component Description
FUEL TEMPERATURE SENSOR (FTS)
The fuel temperature sensor is used to detect the fuel temperature
in the injection pump. The sensor modifies a voltage signal from the
ECM. The modified signal returns to the ECM as the fuel tempera-
ture input. The sensor uses a thermistor which is sensitive to the
change in temperature. The electrical resistance of the thermistor
decreases as temperature increases.
The sensor is built into the inside electrical circuit of the injection
pump.

Component Description
INJECTION TIMING CONTROL VALVE
The injection timing control valve is built into the fuel injection
pump. It controls the timer piston to change the fuel injection tim-
ing.
The timing control valve is a solenoid valve located in the line
between high-pressure chamber and low-pressure chamber. It
changes fuel pressure in the high-pressure chamber.
When current flows through the solenoid (the solenoid turns ON),
the timing control valve opens, advancing fuel injection timing.
When current does not flow through it, the timing control valve
closes, retarding injection timing.
The ECM emits an ON-OFF duty signal. The longer the OFF-
duration, the greater the advance angle. The longer the
ON-duration, the greater the retard angle. This means that chang-
ing the ON-OFF duty ratio makes it possible to achieve an optimal
advance angle and accurately control fuel injection timing.
