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

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
2 terminals respectively to Ad pin and BC pin of regulator, and rated resis-
tance at Engine control system·- EFI systemElectrical
