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).
|
Delivery pipe mounting nut (↔ Fuel feed tube):
18.6 - 23.5 N.m (0.4 - 0.6 kgf.m, 13.7 - 17.4 lb-ft)
|
|
| 8. |
Remove the delivery pipe & injector assembly (A) after loosening the
mounting bolts (B).
|
Delivery pipe mounting bolt:
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.

This gauge shows the temperature of the engine coolant when the ignition switch
is ON.
If the gauge pointer moves beyond the normal range area toward the “H” position,
it indicates overheating that may damage the engine.
