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.

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.
2.CHECK CMP SENSOR ELECTRICAL CONNECTOR
• Disconnect the CMP sensor electrical connector (1).
• Inspect the electrical connector for damage.
Is the electrical connector OK?
Ye s>>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?
Ye s>>Go to step 5.
No
>>Go to the next step.

• Check the following:
Harness connectors A-102, E-105
Front fuse and relay box F3
Fuse 22, Fuse 12
Check harness for open or short between CMP sensor and fuse.
• With the X-431 scan tool, read ECM DTCs.
Is DTC P0016 still present?
Ye s>>Go to the next step.
No
>>The system is now operating properly.
Reassemble the vehicle and road test to verify the customers complaint is repaired.
5.CHECK CMP SENSOR GROUND CIRCUIT FOR AN OPEN AND SHORT
• Turn ignition switch off.
• Check harness continuity between CMP sensor terminal 1 and ground.
• Continuity should exist.
Is the check result normal?
Ye s>>Go to the next step.
No
>>Repair or replace circuit for an open or short to power in harness or connectors.
6.CHECK CMP SENSOR INPUT SIGNAL CIRCUIT FOR AN OPEN AND SHORT
• Turn ignition switch on.
• Check voltage between CMP sensor terminal 2 and ground.
• 11 V should exist.
Is the check result normal?
Ye s>>Go to the next step.
No
>>Repair or replace circuit for an open or short to power or short to ground in harness or connectors.
If circuit is normal, go to the next step.

• Turn ignition switch off.
• Connect CMP sensor connector.
• Check signal voltage between CMP sensor terminal 2 and ground when engine is running.
• Approximately 6 V square wave signal should exist.
ENGINE ANALYZER (KES-200) CMP SENSOR SIGNAL
Is the CMP output signal normal?
Ye s>>Go to step 10.
No
>>Go to the next step.
8.CHECK CMP SENSOR
• Remove the CMP sensor (1).
• Inspect and clean the CMP sensor and mounting
area for any condition that would result in an incor-
rect signal, such as damage, foreign material, or
excessive movement.
Is the mounting area OK?
Ye s>>Go to the next step.
No
>>Repair or replace the sensor as
necessary.

2&3
Is the check result normal?
Ye s>>Replace the CMP sensor with a known good CMP sensor.
Monitor the CMP sensor signal on the KES-200 screen.
If the CMP sensor signals were normal, the system is OK.
If the CMP sensor signals were still irregular or missing, go to step 14.
No
>>Eliminate any condition that would result in an incorrect signal.
