Engine - MIL ON/DTC P2006 Set
TSB: 01-010/07MULTI-MODEL - MIL COMES ON WITH DTC P2006 (VARIABLE SWIRL CONTROL SYSTEM SHUTTER VALVE STUCK CLOSED)
APPLICABLE MODEL(S)/VINS
2006-2007 Mazdaspeed6
2007 Mazda CX-7
2007 Mazdaspeed3
DESCRIPTION
On some vehicles, the MIL comes on with DTC P2006 stored in memory due to the variable swirl shutter valve actuator sticking intermittently in cold weather. This is caused by inadequate spring force in the actuator. To ensure the valve opens, the spring force of the actuator has been increased.
Customers having this concern should have their vehicle repaired using the following repair procedure.
IMPORTANT:
DO NOT alter or modify any portion of the throttle sensor switch.
REPAIR PROCEDURE
1. Verify customer concern.
2. Record the customer's radio presets.
3. Disconnect the negative terminal from the battery.
4. Remove the engine cover.
5. Disconnect the mass air flow (MAF) connector and remove the MAF harness from the clip on the air cleaner cover.
6. Remove the air cleaner cover.
7. Disconnect the vent hose from the air intake hose using the quick disconnect, then remove the air intake hose.
8. Disconnect the air bypass hose from the air bypass valve and the purge valve hose from the purge valve, then move the hoses up out of the way.
9. Disconnect the high pressure fuel spill valve connector.
10. Disconnect the hose from the clip on the wire harness bracket.
11. Remove the two bolts holding the wire harness bracket and move the bracket up and out of the way.
NOTE:
It is not necessary to remove the ground wire bolt or disconnect the connectors as shown.
12. Remove the two bolts from the variable swirl shutter valve actuator.
13. Using a hair dryer (NOT a heat gun), apply approximately 176°F (80°C) heat onto the variable swirl shutter valve actuator ball joint for 3 minutes.
CAUTION:
Do not apply heat higher than 212°F (100°C) because it may cause damage to sensors.
14. Make sure the ball joint gets warm, then disconnect the joint.
CAUTION:
Do not use a tool to disconnect the joint, otherwise the plate could get deformed.
15. Disconnect the variable swirl shutter valve actuator hose, then remove the actuator from the vehicle.
16. Apply approximately 176°F (80°C) heat to the modified variable swirl shutter valve actuator ball joint for 3 minutes, then install the modified actuator.
CAUTION:
In order to prevent the plate from getting deformed, make sure to warm up the joint before the installation.
17. Re-assemble the parts in the reverse order of removal.
NOTE:
For proper alignment, connect the vent hose to the air intake hose before tightening the clamps for the air intake hose.
18. Reprogram the PCM with IDS 47.5 or later software.
19. Verify repair.
20. Enter the customer's radio presets.
