Ye s>>Go to the next step.
No
>>Reinstall CKP sensor.
8.CHECK GEAR TOOTH
• Visually check for chipping signal plate gear tooth.
Is the check result normal?
Ye s>>Go to the next step.
No
>>Replace the signal plate
9.CHECK DTC
• With the X-431 scan tool, read ECM DTCs.

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.
• Run engine for a while 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
