DTC P064D:00 [PCM (SKYACTIV-G (US))]

SM2565535


id0102t43027u0

Note
• To determine the malfunctioning part, proceed with the diagnostics from “Function Inspection Using M-MDS”.



Details On DTCs

Description

Internal control module A/F sensor processor performance problem

Detection condition
Determination conditions
• Malfunction in A/F sensor signal circuit in PCM occurs.
Preconditions
• Battery voltage: 11—18 V *1
*1: Standard can be verified by displaying PIDs using M-MDS
Malfunction determination period
0.1 s period
Drive cycle
• 1
Self test type
• CMDTC self test, KOER self test
Sensor used
• PCM
Fail-safe function
• Not applicable
Vehicle status when DTCs are output
• Not applicable
Possible cause
• PCM malfunction



System Wiring Diagram

• Not applicable



Function Explanation (DTC Detection Outline)

• If there is communication error between the A/F signal control driver and the CPU, the PCM stores a DTC.



Repeatability Verification Procedure

1. Warm up the engine to allow the engine coolant temperature to reach 80 °C {176 °F} or more.
2. Start the engine and leave it idling for 1 min.

Note
• Match the engine coolant temperature in the recorded freeze frame data/snapshot data, the vehicle speed, and engine speed values to the best extent possible while driving the vehicle.
3. Try to reproduce the malfunction by driving the vehicle for 5 min based on the values in the freeze frame data/snapshot data.

Action

1
PURPOSE: VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY
• Verify related Service Bulletins, on-line repair information, or Service Information availability.
• Is any related Information available?
Yes
Perform repair or diagnosis according to the available information.
• If the vehicle is not repaired, go to the next step.
No
Go to the next step.
2
PURPOSE: RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION
• Record the freeze frame data/snapshot data and diagnostic monitoring test results (A/F sensor, HO2S related).

Note
• Recording can be facilitated using the screen capture function of the PC.
Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.



Troubleshooting Diagnostic Procedure

Intention of troubleshooting procedure
• Step 1
― Verify if malfunctioning part is PCM.
• Repair completion verification
― Verify that there are no other malfunctions.

Step

Inspection

Action

1
PURPOSE: PERFORM DTC INSPECTION AND VERIFY IF MALFUNCTIONING PART IS PCM
• Clear the DTC recorded in the memory. (See CLEARING DTC.)
• Replicate the vehicle conditions at the time the DTC was detected using the following procedure.
― Perform the KOER self test. (See DTC INSPECTION.)
• Perform the DTC inspection for the PCM. (See DTC INSPECTION.)
• Is the same Pending DTC present?
Yes
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.
If the CAN communication is normal, replace the PCM and perform the repair completion verification.
No
Go to the next step.
Repair completion verification
PURPOSE: VERIFY IF OTHER DTCs DISPLAYED
• Perform the DTC inspection. (See DTC INSPECTION.)
• Are any other DTCs displayed?
Yes
Repair the malfunctioning location according to the applicable DTC troubleshooting.
No
DTC troubleshooting completed.
