DTC P2006 DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED Has the FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY Check for related Service Bulletins and/or online repair information availability. Is any related repair information available?	Yes	Perform the repair or diagnosis according to the available repair information. If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	CLASSIFY INTERMITTENT CONCERN OR CONTINUOUS CONCERN Clear the DTC from the PCM memory using the WDS or equivalent. Drive the vehicle under following conditions: Engine coolant temperature is above 63°C {145°F}. Engine speed: below 3, 750 RPM Throttle opening angle is as follows: Engine speed below 1, 500 RPM: above 35% Engine speed between 1, 500-2, 500 RPM: between 25-35% Engine speed above 2, 500: below 25% Is the PENDING CODE for this DTC present?	Yes	Go to the next step.
3		No	Intermittent concern exists. Go to INTERMITTENT CONCERN TROUBLESHOOTING procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING ).
4	VERIFY STORED OTHER DTCS Verify stored DTCs using WDS or equipment. Is other DTC present except P0117, P0118, P0121, P0122, P0123 and/or P0335?	Yes	Go to appropriate DTC troubleshooting procedures.
4		No	Go to the next step.
5	INSPECT VARIABLE SWIRL SHUTTER VALVE ACTUATOR Perform the "Variable Swirl System Operation Inspection". (See VARIABLE SWIRL SYSTEM OPERATION INSPECTION ). Is the variable swirl shutter valve actuator normal?	Yes	Go to the next step.
5		No	Replace the variable swirl shutter valve actuator, then go to Step 10.
6	INSPECT VARIABLE SWIRL SOLENOID VALVE Perform the "variable swirl solenoid valve airflow inspection". (See VARIABLE SWIRL SOLENOID VALVE INSPECTION ). Is the variable swirl solenoid valve normal?	Yes	Go to the next step.
6		No	Replace the variable swirl solenoid valve, then go to Step 10.
7	INSPECT VARIABLE SWIRL SOLENOID VALVE OR VARIABLE SWIRL SHUTTER VALVE SW CONNECTOR FOR POOR CONNECTION Turn the ignition switch to off. Disconnect the variable swirl solenoid valve connector and the variable swirl shutter valve switch connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair the terminal, then go to Step 10.
7		No	Go to the next step.
8	INSPECT PCM CONNECTOR FOR POOR CONNECTION Inspect for poor connection at the PCM terminals (such as damaged, pulled-out terminals, corrosion). Is there any malfunction?	Yes	Repair terminal, then go to Step 10.
8		No	Go to the next step.
9	INSPECT VARIABLE SWIRL SOLENOID VALVE OR VARIABLE SWIRL SHUTTER VALVE SWITCH SIGNAL CIRCUIT FOR SHORT TO GROUND Inspect for continuity between the following terminals and body ground. PCM terminal 4K (harness-side). PCM terminal 1N (harness-side). Is there continuity?	Yes	Repair or replace the wiring harness for a short to ground, then go to the next step.
9		No	Go to the next step.
10	VERIFY TROUBLESHOOTING OF DTC P2006 COMPLETED Make sure to reconnect all disconnected connectors. Start the engine. Clear the DTC from the PCM memory using the WDS or equivalent. Start the engine. Drive the vehicle under the following conditions: Engine coolant temperature is above 63°C {145°F}. Engine speed: below 3, 750 RPM Throttle opening angle is as follows: Engine speed below 1, 500 RPM: above 35% Engine speed between 1, 500-2, 500 RPM: between 25-35% Engine speed above 2, 500: below 25% Is the PENDING CODE for this DTC present?	Yes	Replace PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION ).
10		No	Go to the next step.
11	VERIFY AFTER REPAIR PROCEDURE Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE ). Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE ).
11		No	Troubleshooting completed.
