Description

INFOID:0000000004211473

The fuel injector is a small, precise solenoid valve. When the ECM

supplies a ground to the fuel injector circuit, the coil in the fuel injec-

tor is energized. The energized coil pulls the ball valve back and

allows fuel to flow through the fuel injector into the intake manifold.

The amount of fuel injected depends upon the injection pulse dura-

tion. Pulse duration is the length of time the fuel injector remains

open. The ECM controls the injection pulse duration based on

engine fuel needs.

DTC DETECTION LOGIC

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following before conduct-

ing the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1. Turn ignition switch ON (READY) and wait at least 1 second.

2. Check DTC.
Is DTC detected?

YES

>> Go to 

EC-237, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000004211475

1.

CHECK FUEL INJECTOR POWER SUPPLY CIRCUIT

1. Turn ignition switch OFF.

to ECM through the No. 2 fuel injector

• Harness or connectors

(No. 2 fuel injector circuit is open or shorted.)

• No. 2 fuel injector

P0203

No. 3 cylinder fuel injector 
circuit open

An excessively low voltage signal is sent 
to ECM through the No. 3 fuel injector

• Harness or connectors

(No. 3 fuel injector circuit is open or shorted.)

• No. 3 fuel injector

P0204

No. 4 cylinder fuel injector 
circuit open

An excessively low voltage signal is sent 
to ECM through the No. 4 fuel injector

• Harness or connectors

(No. 4 fuel injector circuit is open or shorted.)

• No. 4 fuel injector

4. Check the voltage between fuel injector harness connector and

ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

DETECT MALFUNCTIONING PART

Check the following.

• IPDM E/R harness connector F10

• 10A fuse (No. 35)

• Harness for open or short between fuel injector and fuse

>> Repair open circuit or short to ground or short to power in harness or connectors.

3.

CHECK FUEL INJECTOR OUTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

1. Turn ignition switch OFF.

2. Disconnect ECM harness connector.

3. Check the continuity between fuel injector harness connector and ECM harness connector.

4. Also check harness for short to ground and short to power.
Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair open circuit or short to ground or short to power in harness or connectors.

4.

CHECK FUEL INJECTOR

Refer to 

EC-238, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Replace malfunctioning fuel injector.

5.

CHECK INTERMITTENT INCIDENT

Refer to 

GI-42, "Intermittent Incident"

.

Is the inspection result normal?

YES

>> Replace IPDM E/R.

NO

>> Repair open circuit or short to ground or short to power in harness or connectors.
