DTC P2010 [L3]

BME010202000203

DTC P2010 | Variable tumble control solenoid valve circuit high input
--- | ---
DETECTION CONDITION | • The PCM monitors variable tumble control solenoid valve control signal at PCM terminal 4T. If the PCM turns the variable tumble control solenoid valve on but voltage at PCM terminal 4T still remains high, the PCM determines that the 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. (See DTC CONFIRMATION PROCEDURE [L3].) • Is same DTC present? | Yes | Go to the next step.
No | Intermittent concern exists. Go to INTERMITTENT CONCERN TROUBLESHOOTING procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING [L3].)
2 | INSPECT POOR CONNECTION OF VARIABLE TUMBLE CONTROL SOLENOID VALVE CONNECTOR • Turn the ignition switch off. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there malfunction? | Yes | Repair or replace the terminal, then go to Step 6.
No | Go to the 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 the variable tumble control solenoid valve normal? | Yes | Go to the next step.
No | Replace the variable tumble control solenoid valve, then go to Step 6.
4 | INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the PCM connector. • Inspect for poor connection at PCM terminal 4T (such as damaged/pulled-out pins, corrosion). • Is there any malfunction? | Yes | Repair the terminal, then go to Step 6.
No | Go to the next step.
5 | INSPECT VARIABLE TUMBLE CONTROL SOLENOID VALVE CONTROL CIRCUIT FOR SHORT TO POWER • Remove the variable tumble control solenoid valve. • Turn the ignition switch to the ON position (Engine off). • Measure the voltage between PCM terminal 4T and body ground.
• Is the voltage B+?
Yes
Repair or replace the wiring harness for short to power supply, then go to the next step.
No | Go to the next step.
6 | VERIFY TROUBLESHOOTING OF DTC P2010 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the WDS or equipment. • Perform KOEO/KOER self-test. (See KOEO/KOER SELF-TEST PROCEDURE [L3].)
• Is the PENDING CODE of same DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [L3].)
No | Go to the next step.
7 | VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE [L3].) • Is there any DTC present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [L3].)
No | Troubleshooting completed.
