STEP
INSPECTION
ACTION
5
CHECK PRC SOLENOID VALVE CIRCUIT
CONTINUITY
• Key off.
• Breakout box installed.
• PCM disconnected.
• PRC solenoid valve disconnected.
• Measure resistance between PRC solenoid
valve circuit at PRC solenoid valve vehicle
harness connector and Test Pin 19 at
breakout box.
• Is resistance less than 5.0 ohms?
Yes
REPLACE PCM.
RECONNECT all components.
RERUN OBD Test.
No
SERVICE open circuit.
REMOVE breakout box.
RECONNECT all components.
RERUN OBD Test.
DTC
P1409
EGR valve (Stepper motor) malfunction
DESCRIPTION
• Open or short circuit is observed in EGR valve
[Possible Cause]
• Damaged EGR valve coil
• EGR valve control signal circuit short to ground
• EGR valve control signal circuit open
• EGR valve power circuit open
STEP
INSPECTION
ACTION
1
CHECK CONNECTOR CONNECTION
• Check for connection of EGR valve and
PCM.
• Is connection okay?
Yes
Go to next step.
No
SERVICE as necessary.
RESET PCM to completely clear DTCs.
tr
After Repair Procedure
COMPLETE OBD II Drive Mode.
RERUN OBD Test.
2
CHECK EGR VALVE POWER CIRCUIT
VOLTAGE
• Key off.
• Disconnect EGR valve.
• Key on, engine off.
• Measure voltage between power circuit at
EGR valve harness connector terminal C or
D, and battery negative post.
•
Is each voltage greater than 10.5 volts?
Yes
Go to next step.
No
SERVICE open power circuit.
RECONNECT all components.
RESET PCM to completely clear DTCs.
tr
After Repair Procedure
COMPLETE OBD II Drive Mode.
RERUN OBD Test.
3
CHECK EGR VALVE CONTROL SIGNAL
CIRCUIT SHORT TO GROUND
• Key off.
• EGR valve disconnected.
• Disconnect PCM. Inspect for damaged or
pushed out pins, corrosion, loose wires,
etc. Service as necessary.
• Measure resistance between following
terminals EGR valve connector and battery
negative post.
• Test Pin
68
• Test Pin 72
• Test Pin 46
• Test Pin 56
•
is each resistance greater than 10,000
ohms?
Yes
EGR valve control signal harness circuits to PCM is okay.
Go to next step.
No
SERVICE short circuit between EGR valve control signal
circuit.
RESET PCM to completely clear DTCs.
tr
After Repair Procedure
COMPLETE OBD II Drive Mode.
RERUN OBD Test.
4
CHECK CONTINUITY EGR VALVE
CONTROL SIGNAL CIRCUIT OPEN
• Key off.
• EGR valve disconnected.
• Breakout box installed.
• PCM disconnected.
• Measure resistance between appropriate
Test Pin at the breakout box and EGR
valve terminal at vehicle harness
connector.
• EGR valve terminal E - Test Pin
68
• EGR valve terminal A - Test Pin 72
• EGR valve terminal B - Test Pin 46
• EGR valve terminal F - Test Pin 56
•
Is each resistance less than 5.0 ohms?
Yes
EGR valve control signal harness circuits to PCM is okay.
SERVICE EGR valve
tr
01-16A EGR VALVE INSPECTION [FS]
RESET PCM to completely clear DTCs.
tr
After Repair Procedure

RERUN OBD test.
No
Service open in EGR valve control signal circuit harness.
RECONNECT all components.
RESET PCM to completely clear DTCs.
tr
After Repair Procedure
COMPLETE the OBD II Drive Mode.
RERUN OBD Test.
