Practical checks and shop questions for VVT actuator/correlation codes; save evidence before replacing parts.
This is a non-invasive owner checklist, not an OEM repair procedure or permission to drive.

Codes in this diagnostic topic
These codes share a system-level checklist, but their distinct numbers and meanings are shown below. A code here does not prove a particular vehicle has every listed fault. Use the exact code row and full scan.

|---|---|---|
| P0010 | Bank 1 cam-actuator electrical circuit | Exact vehicle scope unverified |
| P0011 | Bank 1 intake timing too advanced | Exact vehicle scope unverified |
| P0012 | Bank 1 intake timing too retarded | Exact vehicle scope unverified |
| P0014 | Bank 1 exhaust timing too advanced | Exact vehicle scope unverified |
| P0015 | Bank 1 exhaust timing too retarded | Exact vehicle scope unverified |
| P0016 | Bank 1 crank/cam A correlation | Exact vehicle scope unverified |
| P0017 | Bank 1 crank/cam B correlation | Exact vehicle scope unverified |
| P0018 | Bank 2 crank/cam A correlation | Exact vehicle scope unverified |
| P0019 | Bank 2 crank/cam B correlation | Exact vehicle scope unverified |
| P0020 | Bank 2 cam-actuator electrical circuit | Exact vehicle scope unverified |
| P0021 | Bank 2 intake timing too advanced | Exact vehicle scope unverified |
| P0022 | Bank 2 intake timing too retarded | Exact vehicle scope unverified |
| P0024 | Bank 2 exhaust timing too advanced | Exact vehicle scope unverified |
| P0025 | Bank 2 exhaust timing too retarded | Exact vehicle scope unverified |
| P0340 | Camshaft-position sensor circuit fault | Exact vehicle scope unverified |
Save the evidence first
- Full code, bank and A/B sensor suffix
- Oil-pressure warning or mechanical noise
- Oil service history and engine code
Safe owner checks
- If pressure warning or abnormal mechanical noise is present, stop and arrange help.
- Only check oil level using the exact manual, after stopping safely.
Questions for a qualified technician
- Are oil condition/pressure, actuator control, wiring, mechanical timing or calibration responsible?
- Does the BRZ bulletin match the exact vehicle and codes?
Common wrong turns
- A timing code does not prove the cam sensor failed.
- Bank 1/2 and sensor A/B locations are engine-specific.
- Do not follow a generic timing-chain disassembly procedure for a vehicle without the exact service information and qualified equipment.
Confirm the repair
- Verify timing/correlation through approved diagnostics and check for repeat symptoms.
