ACTION
|
|
1
|
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
• Has FREEZE FRAME DATA been recorded?
|
Yes
|
Go to the next step.
|
|
No
|
Record the FREEZE FRAME DATA on the repair order, then go to next step.
|
|
2
|
VERIFY REPAIR INFORMATION AVAILABILITY
• Verify related service repair information availability.
• Is any related repair information available?
|
Yes
|
Perform repair or diagnosis according to the available repair information. If the vehicle is not repaired, go to next step.
|
|
No
|
Go to the next step.
|
|
3
|
INDETIFY TRIGGER DTC FOR FEEZE FRAME DATA
• Is DTC P0443 on FREEZE FRAME DATA?
|
Yes
|
Go to the next step.
|
|
No
|
Go to FREEZE FRAME DATA DTC inspection.
|
|
4
|
INSPECT PURGE SOLENOID VALVE CIRCUIT FOR INTERMITTENT FAILURE
• Rerun KOEO, KOER self test and Continuous Memory DTCs.
• Is DTC P0443 present in Continuous Memory self test only?
|
Yes
|
Intermittent concern exists, go to Intermittent Troubleshooting Procedure.
|
|
No
|
Go to the next step.
|
|
5
|
CHECK POWER SUPPLY VOLTAGE TO PURGE SOLENOID VALVE CIRCUIT
• Turn the ignition switch to OFF.
• Disconnect purge solenoid valve.
• Turn the ignition switch to ON.
• Measure voltage between purge solenoid valve terminal 1 at harness side connector and battery negative post.
• Is voltage greater than 10.5 V?
|
Yes
|
Go to the next step.
|
|
No
|
Repair open circuit, then go to Step 10.
|
|
6
|
CHECK PURGE SOLENOID VALVE RESISTANCE
-
Note
-
• Purge solenoid valve resistance reading must be taken with engine cooled down.
• Disconnect purge solenoid valve.
• Measure purge solenoid valve resistance.
• Is resistance 30-38 ohms?
|
Yes
|
Go to the next step.
|
|
No
|
Replace purge solenoid valve, then go to Step 10.
|
|
7
|
CHECK PURGE SOLENOID VALVE CONTROL CIRCUIT FOR OPEN IN HARNESS
• Disconnect PCM.
• Measure the resistance between PCM terminal 56 (R.H.D.) /C-34 (L.H.D.) and purge solenoid valve terminal 2 at harness side connector.
• Is resistance less than 5.0 ohms?
|
Yes
|
Go to the next step.
|
|
No
|
Repair open circuit, then go to Step 10.
|
|
8
|
CHECK PURGE SOLENOID VALVE CONTROL CIRCUIT FOR SHORT TO GND IN WIRING
• Measure resistance between purge solenoid valve terminal 2 at harness side connector and battery negative post.
• Is resistance greater than 10,000 ohms?
|
Yes
|
Go to the next step.
|
|
No
|
Repair short to GND, then go to Step 10.
|
|
9
|
CHECK PURGE SOLENOID VALVE CONTROL CIRCUIT FOR SHORT TO POWER IN HARNESS
• Turn the ignition switch to ON.
• Measure voltage between purge solenoid valve terminal 2 at harness side connector and battery negative post.
• Is voltage greater than 10.5 V?
|
Yes
|
Repair short to power circuit, then go to the next step.
|
|
No
|
Replace PCM, then go to the next step.
|
|
10
|
VERIFY TROUBLESHOOTING OF DTC P0443 COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear the DTC from the PCM memory using the WDS or equivalent.
• Perform KOEO/KOER self test.
• Is the PENDING CODE same DTC present?
|
Yes
|
Replace PCM, then go to next step.
|
|
No
|
Go to the next step.
|
|
11
|
VERIFY AFTER SERVICE PRECAUTION
• Perform "AFTER SERVICE PRECAUTION".
• Is there any DTC present?
|
Yes
|
Go to applicable DTC inspection.
|
|
No
|
Troubleshooting completed.
