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. |
In the engine control system, failure can be quickly diagnosed by using
the vehicle diagnostic system (KDS).
| (1) |
Self diagnosis : Checking failure and code number (DTC).
|
| (2) |
Current data : Checking the system input/output data state.
|
| (3) |
Actuation test : Checking the system operation condition.
|
| (4) |
Additional function : Controlling other features including system
option setting and zero point adjustment.
|
|
| 1. |
Turn the ignition switch OFF.
|
| 2. |
Disconnect the injector connector.
|
| 3. |
Measure resistance between the injector terminals 1 and 2.
|
| 4. |
Check that the resistance is within the specification.
|
Specification : Refer to "Specification"
|
|
| 1. |
Remove the injector from the delivery pipe.
(Refer to Fuel Delivery System - "Injector")
|
| 1. |
Install in the reverse order of removal.
|
|
Note the followings when mounting the injector on the delivery pipe.
| • |
If reused the injector, replace the O-ring (A) and clip (B).
|
| • |
Apply engine oil to the injector O-ring.
|
| • |
When insert the injector, be careful not to damage the O-ring.
