Engine control systemEFI systemOn-vehicle inspection1. Inspection of the voltage of power steering oil pres-
sure sensorMeasure the voltage between PS terminal and E2 terminal
with ohmmeter2. Inspection of stepping motor(a) With engine running at idle speed, pull out the connection harness of stepping motor, and the change
of engine rotating speed indicates that the stepping motor operates normally.
(b) Pull out the connection harness of stepping motor, and measure the terminal current with universal
meter. When engine is running, there being impulse current output at the terminal indicates that there
is no trouble with ECU and stepping motor control system, and if idling is not stable at the moment
and deviates greatly from specified value, the stepping motor should be replaced. If there is no
impulse current output at the terminal, turn on air conditioner to test again, and still no impulse
current output indicates that there is trouble with ECU and stepping motor control system circuit.
(c) Check the malfunction of stepping motor circuit with diagnostic instrument.Engine control system·- EFI system 8Conditions Voltage (V) Not turning steering wheel with

Engine control system·- EFI systemInspection1. VVT control solenoid valve assembly (4G18-1006200)(a) Resistance inspection
(1) Measure the resistance between terminals with ohmmeter
Resistance: (b) Operation inspection
Connect battery positive (+) wire to No.1 terminal and negative (-) wire to No. 2 terminal, and check
valve operation.
Note: ensure that the valve is not stuck.
Hint: if there are foreign matters in the valve, the valve could not be closed tightly and will
thus result in slight pressure being lifted toward higher direction.2. Throttle body components (4G18-1001240)(a) Inspection of throttle body
(1) Throttle valve shaft should not swing.
(2) All channels should not be blocked.
(3) Throttle valve plate should rotate flexibly and act smoothly.
(4) When the throttle is at closed position, there should be no clearance between throttle stop bolts and
throttle lever.
Note: it is not allowed to adjust the throttle stop bolts.3. Throttle position sensor (4G18-3600080)(a) Resistance inspection
(1) Remove the wiring harness connectors of throttle posi-
tion sensor.
(2) Measure the resistance between 1# pin and 2# pin with
ohmmeter, resistance value: .
(3) Connect 2 terminals respectively to 1# pin and 3# pin,
and turn the throttle, the resistance value varies linearly
with the opening of throttle, but 2# pin and 3# pin are
contrary to this.
Note:pay attention whether there is great jump with
resistance value when observing resistance change. 9

5. Water temperature sensor (4G18-3600040)This sensor applies sealing NTC thermal resistor in temperature sensor, and resistance value varies with
ambient temperature, thus slight change of outside temperature could be measured. Measuring its out-
put resistance could reflect the temperature of contact media. Signals from A and C are sent to ECU,
and Signals from B and earth are sent to instrument.
Operating principle (Fig. 1):
Note: A, B and C represent 3 pins of sensor, and see pin root for the mark. Measuring method:
(Removing the joint) place digital universal meter at ohm gear,
and connect 2 terminals respectively to 1#
pin and 2#
pin, and
the resistance under normal temperature should be more than
1M. Place digital universal meter at millivolt gear, and knock
around knock sensor with a hand hammer, there should be voltage
signal output at the moment.Engine control system·- EFI systemFig. 11 Vibration block

Characteristic curve of intake air

temperature sensorStepping motor ofidle speed actuator6. Intake air temperature sensor (4G18-3600090)Intake air temperature sensor is a resistor with negative tem-
perature coefficient (NTC), resistance varies with intake air
temperature, and this sensor sends a voltage indicating change
of intake air temperature to controller.
Simple measuring method:
(Removing the joint) place digital universal meter at ohm gear,
and connect 2 terminals respectively to 1# pin and 2# pin of
sensor, and rated resistance at 5%, and
other corresponding resistance values could be measured ac-
cording to the characteristic curve in above drawing. Analog
method could also be applied in measurement. Use an elec-
tric blower to blow air into the sensor (pay attention not to
keep them too near), and observe the change of resistance,
which should decrease at the moment.7. Stepping motor (4G18-3600070)Schematic diagram and pinsEngine control system·- EFI systemUse digital universal meter to measure:

Pins: Pin A is connected to ECU No. 65 pin
Pin B is connected to ECU No. 66 pin
Pin C is connected to ECU No. 67 pin
Pin D is connected to ECU No. 64 pin
Maintenance precautions:
1. It is not allowed to apply any force at axial direction with the purpose of pressing into or pulling out the
axle;
2. Before idle speed regulator with stepping motor is mounted into throttle body, its shaft must be at fully
retractive position;
3. Pay attention to clean and maintain bypass air passage frequently;
4. After removing battery or ECU, pay attention to self-teach stepping motor in time.
Self-teach method of M7 system: turn on ignition switch but not start engine immediately, and start it
after 5 seconds. If engine idle speed is found bad at the moment, it is
necessary to repeat the above steps.
Simple measuring method:(removing the joint) place digital universal meter at ohm gear, and connect
