DTC
P0443
Evaporative emission control system purge solenoid valve circuit malfunction
DESCRIPTION
• DTC P0443 indicates failure in purge solenoid valve circuit
[Possible Cause]
• Power circuit open
• Damaged purge solenoid valve
• Purge solenoid valve signal open in harness
• Damaged PCM
• Purge solenoid valve signal circuit short to power ground
STEP
INSPECTION
ACTION
1
CHECK PURGE SOLENOID VALVE POWER
CIRCUIT
Note
• If DTC P0443 was generated in continuous
memory only, go to step 5.
• Key off.
• Disconnect purge solenoid valve.
• Key on, engine off.
• Measure voltage between power circuit at
purge solenoid valve vehicle harness
connector and battery ground.
•
is voltage greater than
1
0.5 volts?
Yes
Go to next step.
No
SERVICE open in power circuit harness circuit.
RECONNECT all components.
VERIFY symptom no longer exists.
RESET PCM to completely clear DTCs.
tr
After Repair Procedure
COMPLETE OBD II Drive Mode.
RERUN OBD Test.
2
CHECK PURGE SOLENOID VALVE
RESISTANCE
• Key off.
• Purge solenoid valve disconnected.
• Measure resistance between purge
solenoid valve signal and power circuit at
purge solenoid valve.
•
Is resistance between
27
and 35 ohms?
Yes
Go to next step.
No
REPLACE purge solenoid valve.
VERIFY the symptom no longer exists.
RESET PCM to completely clear DTCs.
o* After Repair Procedure
COMPLETE OBD II Drive Mode.
RERUN OBD Test.
3
CHECK CONTINUITY OF PURGE
SOLENOID VALVE SIGNAL CIRCUIT
• Key off.
• Purge solenoid valve disconnected.
• Disconnect PCM. Inspect for damaged or
pushed out pins, corrosion, loose wires,
etc. Service as necessary.
• Install breakout box. Leave PCM
disconnected.
• Measure resistance between Test Pin 67 at
breakout box and purge solenoid valve
signal circuit at solenoid vehicle harness
connector.
• Is the resistance less than 5.0 ohms?
Yes
Go to next step.
No
SERVICE open in harness circuit.
REMOVE breakout box.
RECONNECT all components.
VERIFY symptom no longer exists.
RESET PCM to completely clear DTCs.
tr
After Repair Procedure
COMPLETE OBD II Drive Mode.
RERUN OBD Test.
4
CHECK PURGE SOLENOID VALVE SIGNAL
CIRCUIT FOR SHORT GROUND CIRCUIT
• Key off.
• Purge solenoid valve disconnected.
• Breakout box installed.
• Disconnect NGS tester from DLC.
• Measure the resistance between Test Pin
67 and Test Pins 24 and 103 at breakout
box.
•
Is each resistance greater than
1
0,000
ohms?
Yes
Go to next step.
No
SERVICE harness short circuit.
REMOVE breakout box.
RECONNECT all components.
VERIFY symptom no longer exists.
RESET PCM to completely clear DTCs.
o * After Repair Procedure
COMPLETE OBD II Drive Mode.
RERUN OBD Test.
5
COMPLETED KOEO AND KOER SELF-TEST
• Was
DTC P0443
generated in either
KOEO or KOER self-test?
Yes
RETURN to step 1 and address the cause of the DTC.
No
Go to next step.
