DTC P061C:00 [MZ-CD 1.6]

id0102g8315000

DTC P061C:00

Internal control module engine RPM performance
DETECTION CONDITION
•  For safety reasons, the PCM compares the engine speed calculated from the CKP sensor signal and the engine speed calculated from the PCM software timer. If difference between the two engine speed values exceeds the threshold, the PCM determines that there is a malfunction in the internal control module.
POSSIBLE CAUSE
•  CKP sensor installation improper
•  CKP sensor pulse wheel damaged
•  Foreign matter adhering to CKP sensor
•  Open or short circuit in wiring harness between CKP sensor and PCM:
―  CKP sensor terminal A and PCM terminal 3AE
―  CKP sensor terminal B and PCM terminal 3AM
―  CKP sensor terminal C and PCM terminal 3C
•  CKP sensor malfunction
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record FREEZE FRAME DATA on repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related service information availability.
•  Is any related service information available?
Yes
Perform repair or diagnosis according to available service information.
•  If vehicle is not repaired, go to the next step.
No
Go to the next step.
3
VERIFY RELATED PENDING CODE AND/OR DTC
•  Switch the ignition to ON (engine off).
•  Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure.
•  Is the other PENDING CODE/DTC also present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [MZ-CD 1.6].)
No
Go to the next step.
4
VISUALLY INSPECT CKP SENSOR INSTALLATION
•  Visually inspect the CKP sensor installation.
•  Is there a mis-installation or foreign matter adhering to the detection area?
Yes
Install correctly or remove the foreign matter, then go to Step 10.
(See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION [MZ-CD 1.6].)
No
Go to the next step.
5
INSPECT CKP SENSOR PULSE WHEEL
•  Visually inspect the CKP sensor pulse wheel (crankshaft pulley).
•  Is there any malfunction?
Yes
Replace the crankshaft pulley, then go to Step 10.
(See TIMING BELT REMOVAL/INSTALLATION [MZ-CD 1.6].)
No
Go to the next step.
6
INSPECT CKP SENSOR CIRCUIT FOR SHORT TO GROUND CIRCUIT
•  Switch the ignition to off.
•  Disconnect the CKP sensor connector.
•  Inspect for continuity between each CKP sensor terminals (wiring harness-side) and body ground.
•  Is there any continuity?
Yes
If the short to ground circuit could be detected:
•  Repair or replace the wiring harness for a possible short to ground.
If the short to ground circuit could not be detected:
•  Replace the PCM (short to ground in PCM internal circuit).
Go to Step 10.
No
Go to the next step.
7
INSPECT CKP SENSOR CIRCUIT FOR SHORT TO POWER SUPPLY CIRCUIT
•  CKP sensor connector is disconnected.
•  Disconnect the PCM connector.
•  Switch the ignition to ON.
•  Measure the voltage between each CKP sensor terminals (wiring harness-side) and body ground.
•  Is there any voltage?
Yes
Repair or replace the wiring harness for a possible short to power supply circuit, then go to Step 10.
No
Go to the next step.
8
INSPECT CKP SENSOR CIRCUIT FOR OPEN CIRCUIT
•  Switch the ignition to off.
•  CKP sensor and PCM connectors are disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side):
―  CKP sensor terminal A—PCM terminal 3AE
―  CKP sensor terminal B—PCM terminal 3AM
―  CKP sensor terminal C—PCM terminal 3C
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to Step 10.
9
INSPECT CKP SENSOR
•  Inspect the CKP sensor.
•  Is there any malfunction?
Yes
Replace the CKP sensor, then go to Step.
(See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION [MZ-CD 1.6].)
No
Intermittent concern exists.
Go to the next step.
10
VERIFY THAT DTC P061C:00 TROUBLESHOOTING IS COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the memory using the M-MDS.
•  Run the vehicle under the FREEZE FRAME DATA stored condition.
•  Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [MZ-CD 1.6].)
No
Go to the next step.
11
VERIFY AFTER REPAIR PROCEDURE
•  Perform the after repair procedure.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [MZ-CD 1.6].)
No
DTC troubleshooting completed.
