| SUBJECT: | Diagnosis and Repair for AVCS-Related DTCs P000A, P000B, P000C, P000D, P0011, P0014, P0021 and P0024 |
INTRODUCTION
This Bulletin provides a procedure for diagnosis and determination of necessary part replacement in the event any of the “AVCS Slow Response” or “AVCS System Failure” DTCs listed above are found to be stored in the ECM memory. A possible cause of these conditions is contamination within the camshaft sprocket and / or oil control solenoid valve (OCV) mechanism.
COUNTERMEASURE IN PRODUCTION
Countermeasures were incorporated into production during July, 2012 starting with the following VINs:
| MODEL | VEHICLE TYPE | STARTING VIN FOR CAMSHAFT SPROCKET COUNTERMEASURE | STARTING VIN FOR OIL CONTROL SOLENOID VALVE COUNTERMEASURE |
|---|---|---|---|
| BRZ | – | D*603215 | D*603362 |
| Impreza and XV Crosstrek (Exc. WRX & STI) | 4-Door | D*004206 | D*004655 |
| 5-Door | D*204371 | D*205723 | |
| Legacy | – | D*006591 | D*006243 |
| Outback | – | D*213584 | D*212977 |
| Forester | – | D*417742 | D*419507 |
SERVICE PROCEDURE / INFORMATION
NOTES: Only the Intake-related DTCs are applicable to Legacy, Outback and Forester models.
- Using the SSMIII, determine which DTC is stored.
- Determine the location of the suspect component using the DTC List on page 3.
- Swap the Oil Control Solenoid Valves side-to-side (intake to intake or exhaust to exhaust, not between intake and exhaust on same side) following the procedure in the applicable Service Manual.
NOTE: The o-ring and nylon backer ring on the OCV must be replaced prior to reinstallation as they both are one-time use items.
- Clear the ECM memory.
- Perform the model-specific Drive Cycle or Inspection Mode procedure for the corresponding DTC as shown in the chart on the next page.
- Follow the applicable procedure below for locating either Inspection Mode or Drive Cycle instructions to coincide with the reference chart found on page 3.
- For BRZ: Using the Service Diagnostics tab on the STIS home page, enter your vehicle search parameters (example: 2013 > BRZ). Next, using the DTC tab, enter P0021 for INTAKE-related DTCs or P0024 for EXHAUST-related DTCs. Select the applicable link from your search result (example: P0021: Camshaft Position “A” – Timing Over-Advanced or System Performance (Bank 2)). Follow the diagnostic outline down to TEST DRIVE (for Drive Cycle) information.
- For All Other : Using the Service Diagnostics tab on the STIS home page, enter your vehicle search parameters (example: 2013 > Outback). Next, enter specific DTC into the search term box. Select the applicable link from your search result (examples: ENGINE (DIAGNOSTICS) (H4DO) > Drive Cycle > PROCEDURE or ENGINE (DIAGNOSTICS) (H4DO) > Inspection Mode > PROCEDURE).

- Does the suspect component / problem location change to the opposite bank of the engine by resetting the applicable DTC?
- YES– Replace the suspect OCV with a new part (including a new o-ring and backer ring).
- NO– Replace the suspect camshaft sprocket with a new part. (It is not necessary to return OCVs to their original positions.)
IMPORTANT: After any component replacement, perform the applicable Drive Cycle or Inspection Mode procedure again to confirm the repair.
