DTC P2010 | Variable tumble solenoid valve circuit high input
--- | ---
DETECTION CONDITION | • The PCM monitors the variable tumble solenoid valve control signal. If the PCM turns variable tumble solenoid valve on but the voltage still remains high, the PCM determines that the variable tumble solenoid valve circuit has a malfunction. Diagnostic support note • This is a continuous monitor (CCM). • The MIL illuminates if the 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 the PCM detects the above malfunction condition during first drive cycle. • FREEZE FRAME DATA is available. • Are any DTCs is stored in the PCM memory.
POSSIBLE CAUSE | • Poor connection of connectors at PCM and/or variable tumble solenoid valve • Short to power supply in wiring harness between variable tumble solenoid valve terminal B and PCM terminal 2I • Variable tumble solenoid valve malfunction • PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded? | Yes | Go to the next step.
No | Record the FREEZE FRAME on the repair order, then go to the next step.
2 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available? | Yes | Perform repair or diagnosis according to the available Service information. If the vehicle is not repaired, go to the next step.
No | Go to the next step.
3 | INSPECT VARIABLE TUMBLE SOLENOID VALVE CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction? | Yes | Repair or replace the terminal, then go to Step 7.
No | Go to the next step.
4 | INSPECT VARIABLE TUMBLE SOLENOID VALVE • Inspect the variable tumble solenoid valve. (See VARIABLE TUMBLE SOLENOID VALVE INSPECTION [L8, LF, L3].) • Is the variable tumble solenoid valve normal? | Yes | Go to the next step.
No | Replace the variable tumble solenoid valve, then go to Step 7.
5 | INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the PCM connector. • Inspect for poor connection at PCM terminal 2I. (such as damaged/pulled-out pins, corrosion). • Is there any malfunction? | Yes | Repair the terminal, then go to Step 7.
No | Go to the next step.
6 | INSPECT VARIABLE TUMBLE SOLENOID VALVE CONTROL CIRCUIT FOR SHORT TO POWER SUPPLY • Remove the variable tumble solenoid valve. • Turn the ignition switch to the ON position (Engine off). • Measure the voltage between PCM terminal 2I and body ground. • Is the voltage B+? | Yes | Repair or replace the wiring harness with short to power supply, then go to the next step.
No | Go to the next step.
7 | VERIFY TROUBLESHOOTING OF DTC P2010 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the WDS or equivalent. • Start the engine. • Is the PENDING CODE for this DTC present? | Yes | Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L8, LF, L3].)
No | Go to the next step.
8 | VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [L8, LF, L3].) • Is any DTC present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [L8, LF, L3].)
No | Troubleshooting completed.
