• Turn ignition switch on.
• Check injector supply voltage between sensor ter-
minal and ground in the electrical connector.
• Battery voltage should exist.
Is the check result normal?
Ye s>>Go to step 8.
No
>>Go to the next step.
7.DETECT MALFUNCTIONING PART
• Check the following:
Harness connectors A-102, E-105
Front fuse and relay box F3
Fuse 12, fuse 23, fuse 24
Harness for an open or short between injector and fuse
Is the check result normal?
Ye s>>With the X-431, check the system, If OK, go to the next step.
No
>>Repair malfunctioning part.
8.CHECK INJECTOR CONTROL CIRCUITS FOR A SHORT
• Check injector control circuit voltage.
• 3.6 V should exist.
Is the check result normal?
Ye s>>Go to step 10.
No
>>Go to the next step.
9.DETECT MALFUNCTIONING PART
• Turn ignition switch off.
• Disconnect ECM harness connector.
• Check if the injector control circuits short to power supply circuits.
• Check the following.
• Voltage should not exist.

DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Turn ignition switch off.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.
• Turn ignition switch on.
• With the scan tool, record and erase stored DTCs in the ECM.
• Start engine and warm it to normal operating temperature then select view DTC.
• If DTC is detected, go to Diagnostic Procedure - Step 1.
• If the DTC is not detected, the DTC condition is intermittent (See Diagnosis & Testing Diagnostic Help in Sec-
tion 03 Electronic Engine Controls).
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
Diagnostic Procedure
1.CHECK GROUND CONNECTIONS
• Turn ignition switch off.
• Loosen and retighten ground screws on the body (See Ground Inspection in Section 03 Electronic Engine Con-
trols).
• Inspect ground connections E-207 and E-208 mounting position (See Vehicle Wiring Harness Layout - Engine
Room Harness (With 2.0L Engine) in Section 16 Wiring).
Are the ground connections OK?
Ye s>>Go to the next step.
No
>>Repair or replace ground harness or connections.
