DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Connect the X-431 scan tool to the diagnostic connector (DLC) - use the most current software available, press
the POWER key to start the X-431.
• Turn ignition switch on and record and erase DTC.
• Start engine and warm it up to the normal operating temperature.
• With the scan tool, select view DTC and data stream.
• If the DTC is detected, the DTC condition is current. Go to Diagnostic Procedure - Step 1.
• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-
bleshooting in Section 03 Electronic Engine Controls for more information.
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
DIAGNOSIS & TESTING
03
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?
Yes
>>
Go to the next step.
No
>>
Repair or replace ground harness or connections.
2.
CHECK CMP SENSOR ELECTRICAL CONNECTOR
• Disconnect the CMP sensor electrical connector (1).
• Inspect the electrical connector for damage.
Is the electrical connector OK?
Yes
>>
Go to the next step.
No
>>
Repair or replace the electrical connector
as necessary.
3.
CHECK CMP SENSOR POWER SUPPLY CIRCUIT FOR AN OPEN OR SHORT
• Turn ignition switch on.
• Check CMP sensor supply voltage between sensor
connector E-007, terminal 3 and ground in the sen-
sor electrical connector.
• Battery voltage should exist.
Is the check result normal?
Yes
>>
Go to step 5.
No
>>
Go to the next step.
