Description and operation
Based on information from various sensors, the ECM can calculate the fuel amount
to be injected. The fuel injector is a solenoid-operated valve and the fuel injection
amount is controlled by length of injection time. The ECM controls each injector
by grounding the control circuit. When the ECM energizes the injector by grounding
the control circuit, the circuit voltage should be low (theoretically 0V) and the
fuel is injected. When the ECM de-energizes the injector by opening control circuit,
the fuel injector is closed and circuit voltage should momentarily peak.

Repair procedures
| 1. |
Turn ignition switch OFF.
|
| 2. |
Disconnect injector connector.
|
| 3. |
Measure resistance between injector terminals 1 and 2.
|
| 4. |
Check that the resistance is within the specification.
|

|
| 1. |
Release the residual pressure in fuel line.
(Refer to “Release Residual Pressure in Fuel Line” in this group).
|
| 2. |
Turn the ignition switch OFF and disconnect the battery negative (-)
terminal.
|
| 3. |
Remove the engine cover.
(Refer to Engine And Transaxle Assembly - "Engine Cover")
|
| 4. |
Remove the wiring harness after loonsening the mounting bolts.
|
| 5. |
Disconnect the injector connector (A).
|
| 6. |
Remove the PCV hose (A).
|
| 7. |
Disconnect the fuel feed tube (A) after loosening the mounting nuts (B).

7.8 - 11.8 N.m (1.9 - 2.4 kgf.m, 5.8 - 8.7 lb-ft)
|
|
| 9. |
Remove the fixing clip (A), and then separate the injector from the delivery
pipe.
|
| • |
Install the component with the specified torques.
|
| • |
Note that internal damage may occur when the component is dropped.
In this case, use it after inspecting
|
| • |
Apply the engine oil to the injector O-ring.
|
| • |
Inspect the injector O-ring when installing.

Other information:
The cruise control system allows you to program the vehicle to maintain a constant
speed without depressing the accelerator pedal.
This system is designed to function above approximately 30 km/h (20 mph).

Description and operation
Description
Due to the considerably more frequent occurrence of starting operations, the
electrical load that occurs often leads to voltage dips in the vehicle network.
In order to stabilize the power supply for certain voltage-sensitive electrical
