DTC P0661
A6E397001088W03
Diagnostic procedure
DTC P0661
Variable intake-air system (VIS) contol solenoid valve circuit low input
DETECTION
CONDITION
•
PCM monitors VIS control solenoid valve control signal at PCM terminal 4R. If PCM turns VIS control
solenoid valve off but voltage at PCM terminal 4R still remains low, PCM determines that VIS control
solenoid valve circuit has malfunction.
POSSIBLE
CAUSE
•
VIS control solenoid valve malfunction
•
Open circuit in wiring between main relay and VIS control solenoid valve terminal B
•
Open circuit in wiring between VIS control solenoid valve terminal A and PCM terminal 4R
•
Short to ground in wiring between VIS control solenoid valve terminal A and PCM terminal 4R
•
Connector or terminal malfunction
•
PCM malfunction
STEP
INSPECTION
ACTION
1
PERFORM DTC CONFIRMATION PROCEDURE
•
Perform DTC CONFIRMATION PROCEDURE.
(See
F–66 DTC CONFIRMATION
PROCEDURE
.)
•
Is same DTC present?
Yes Go to next step.
No
Intermittent concern exists. Go to INTERMITTENT
CONCERN TROUBLESHOOTING procedure.
(See
F–227 INTERMITTENT CONCERN
TROUBLESHOOTING
.)
2
INSPECT VIS CONTROL SOLENOID VALVE
CONNECTOR FOR POOR CONNECTION
•
Turn ignition key to OFF.
•
Disconnect VIS control solenoid valve
connector.
•
Inspect for poor connection (damaged/pulled-
out pins, corrosion, etc.).
•
Is there malfunction?
Yes Repair or replace terminal, then go to Step 8.
No
Go to next step.
3
INSPECT VIS CONTROL SOLENOID VALVE
MALFUNCTION
•
Perform VIS control solenoid valve inspection.
(See
F–14 VARIABLE INTAKE-AIR SYSTEM
(VIS) CONTROL SOLENOID VALVE
INSPECTION (L3)
.)
•
Is VIS solenoid valve okay?
Yes Go to next step.
No
Replace VIS control solenoid valve, then go to step 8.
4
INSPECT VIS CONTROL SOLENOID VALVE
POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT
•
Turn ignition key to ON (Engine OFF).
•
Measure voltage between VIS control solenoid
valve terminal B (harness-side) and body
ground.
•
Is voltage
B+
?
Yes Go to next step.
No
Repair or replace harness for open, then go to Step 8.
