DTC P2009 [L3]

BME010202000W02

DTC P2009 | Variable tumble control solenoid valve circuit low input
--- | ---
DETECTION CONDITION | • PCM monitors variable tumble control solenoid valve control signal at PCM terminal 4T. If PCM turns variable tumble control solenoid valve off but voltage at PCM terminal 4T still remains low, PCM determines that variable tumble control solenoid valve circuit has malfunction. Diagnostic support note
• This is a continuous monitor (CCM).
• MIL illuminates if PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
• PENDING CODE is available if PCM detects the above malfunction condition during first drive cycle.
• FREEZE FRAME DATA is available.
• DTC is stored in PCM memory.
POSSIBLE CAUSE | • Poor connection of connectors at PCM and/or variable tumble control solenoid valve • Short to ground in wiring between variable tumble control solenoid valve terminal B and PCM terminal 4T • Open circuit in wiring between main relay and variable tumble control solenoid valve terminal A
• Open circuit in wiring between variable tumble control solenoid valve terminal B and PCM terminal 4T
• Variable tumble control solenoid valve malfunction
• PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | PERFORM DTC CONFIRMATION PROCEDURE • Perform DTC CONFIRMATION PROCEDURE. (See DTC CONFIRMATION PROCEDURE [L3].) • Is same DTC present? | Yes | Go to next step.
No | Intermittent concern exists. Go to INTERMITTENT CONCERN TROUBLESHOOTING procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING [L3].)
2 | INSPECT VARIABLE TUMBLE CONTROL SOLENOID VALVE CONNECTOR FOR POOR CONNECTION • Turn ignition key to OFF. • Inspect for poor connection (damaged/pulled-out pins, corrosion, etc.). • Is there any malfunction? | Yes | Repair or replace terminal, then go to Step 8.
No | Go to next step.
3 | INSPECT VARIABLE TUMBLE CONTROL SOLENOID VALVE • Perform variable tumble control solenoid valve inspection. (See VARIABLE TUMBLE CONTROL SOLENOID VALVE INSPECTION [L3].) • Is variable tumble control solenoid valve okay? | Yes | Go to next step.
No | Replace variable tumble control solenoid valve, then go to Step 8.
4 | INSPECT VARIABLE TUMBLE CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT • Disconnect variable tumble control solenoid valve connector. • Turn ignition key to ON (Engine OFF). • Measure voltage between variable tumble control solenoid valve terminal A (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.
5 | INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn ignition key to OFF. • Disconnect PCM connector. • Inspect for poor connection at PCM terminal 4T. (damaged/pulled-out pins, corrosion, etc.). • Is there any malfunction? | Yes | Repair terminal, then go to Step 8.
No | Go to next step.
6 | INSPECT VARIABLE TUMBLE CONTROL SOLENOID VALVE CONTROL CIRCUIT FOR SHORT TO GROUND • Inspect continuity between variable tumble control solenoid valve terminal B (harness-side) and body ground. • Is there continuity? | Yes | Repair or replace harness for short to ground, then go to Step 8.
No | Go to next step.
7 | INSPECT VARIABLE TUMBLE CONTROL SOLENOID VALVE CONTROL CIRCUIT FOR OPEN CIRCUIT • Connect variable tumble control solenoid valve connector. • Turn ignition key to ON (Engine OFF). • Measure voltage between PCM terminal 4T (harness side) and body ground.
• Is voltage B+?
Yes
Go to next step.
No | Repair or replace harness for open or short to ground circuit, then go to next step.
8 | VERIFY TROUBLESHOOTING OF DTC P2009 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear DTC from PCM memory using WDS or equipment. • Perform KOEO/KOER self-test. (See KOEO/KOER SELF-TEST PROCEDURE [L3].)
• Is same DTC present?
Yes
Replace PCM, then go to next step.
(See PCM REMOVAL/INSTALLATION [L3].)
No | Go to next step.
9 | VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE [L3].) • Is there any DTC present? | Yes | Go to applicable DTC troubleshooting. (See DTC TABLE [L3].)
No | Troubleshooting completed.
