CIRCUIT DESCRIPTION
When the ignition switch is turned on, battery positive voltage is applied to the coil, closing the
contacts of the EFI main relay and supplying power to the terminals + B and + 131 of the ECM.

CIRCUIT DESCRIPTION
Fuel pump control
The fuel pump is switched on (low voltage at terminal FC) when STA is on or while the NE signal
is input to the ECM.
In the diagram below, when the engine is cranked, current flows from terminal ST of the ignition
switch to the starter relay coil, the starter relay switches on and current flows to coil L1 of the circuit
opening relay. Thus the circuit opening relay switches on, power is supplied to the fuel pump and the
fuel pump operates.
When the STA signal and NE signal are input to the ECM, Tr is turned ON, current flows to coil L2
of the circuit opening relay, the relay switches on and the fuel pump operates.
While the NE signal is generated (engine running), the ECM keeps Tr ON (circuit opening relay ON)
and the fuel pump also keeps operating.

5S±FE ENGINE
DESCRIPTION
The 5S±FE engine has improved the torque in the low±to±mid±speed range through improvements made for the intake
and exhaust systems and the combustion chamber. In addition, its exhaust emissions have been reduced through the
improvements made for the exhaust system and the engine control system.

IGNITION SYSTEM
1. General
A DIS (Direct Ignition System) has been adopted in the new 5S±FE engine. The DIS in new 5S±FE engine is a
2±cylinder simultaneous ignition system which ignites 2±cyliners simultaneously with one ignition coil. In addition,
the igniter is integrated in the ignition coil for simpler system configuration.
2. Ignition Coil
Construction of the DIS system of the 5S±FE engine consists of 2 sets of ignition coils integrated with igniter and
with the high±tension cords attached directly onto the ignitioncoil.

Camshaft Position Sensor
The camshaft position sensor is mounted onto the
cylinder head. Using the protusion that is provided
on the timing pulley, the sensor generates 1 signal
for every revolution. This signal is then sent to the
ECM as a cranskshaft angle system.
