DTC P2010 [L3]

BME010202000W03

DTC P2010

Variable tumble control solenoid valve circuit high input

DETECTION CONDITION

• PCM monitors variable tumble control solenoid valve control signal at PCM terminal 4T. If PCM turns variable tumble control solenoid valve on but voltage at PCM terminal 4T still remains high, 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 power 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.
• Is same DTC present?
Yes
Go to next step.
No
Intermittent concern exists. Go to INTERMITTENT CONCERN TROUBLESHOOTING procedure.
2
INSPECT POOR CONNECTION OF VARIABLE TUMBLE CONTROL SOLENOID VALVE CONNECTOR
• Turn ignition key to OFF.
• Inspect for poor connection (damaged/pulled-out pins, corrosion, etc.).
• Is there malfunction?
Yes
Repair or replace terminal, then go to Step 6.
No
Go to next step.
3
INSPECT VARIABLE TUMBLE CONTROL SOLENOID VALVE
• Perform variable tumble control solenoid valve inspection.
• Is variable tumble control solenoid valve okay?
Yes
Go to next step.
No
Replace variable tumble control solenoid valve, then go to Step 6.
4
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 6.
No
Go to next step.
5
INSPECT VARIABLE TUMBLE CONTROL SOLENOID VALVE CONTROL CIRCUIT FOR SHORT TO POWER
• Remove variable tumble control solenoid valve.
• Turn ignition key to ON (Engine OFF).
• Measure voltage between PCM terminal 4T and body ground.
• Is voltage B+?
Yes
Repair or replace harness for short to power circuit, then go to next step.
No
Go to next step.
6
VERIFY TROUBLESHOOTING OF DTC P2010 COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear DTC from PCM memory using WDS or equipment.
• Perform KOEO/KOER self-test.
• Is PENDING CODE of same DTC present?
Yes
Replace PCM, then go to next step.
No
Go to next step.
7
VERIFY AFTER REPAIR PROCEDURE
• Perform "After Repair Procedure".
• Is there any DTC present?
Yes
Go to applicable DTC troubleshooting.
No
Troubleshooting completed.
