P0025
Camshaft Position Timing Over-Retarded (Bank 2 Exhaust)
Severity
medium
Worth booking. It costs fuel, emissions or comfort until it is fixed.
Can you drive it
Only if running normally
A short trip to a shop may be reasonable if the light is steady and the car runs normally. Stop safely for a flashing light, severe shaking, overheating, loss of power, or another urgent warning. The code alone cannot confirm safety.
Indicative cost (USD)
$150–$800

How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then work the likely-causes list in the order shown.
That order is what a shop checks first for this code — wiring and connections before the component they run to, because a connector costs nothing to inspect and is a common answer.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

P0025 is the Bank 2 'A' (intake on most platforms, exhaust on a few — verify with the OEM service manual before throwing parts) camshaft position range/performance code, which the ECM sets when the actual cam angle deviates from commanded by more than roughly 6 to 10 crank degrees, or when the phaser fails to reach within 5 degrees of target within the timeout window (commonly 2 to 5 seconds depending on calibration).
Cheapest-first ladder
- confirm oil level and condition (a phaser cannot hold position on aerated or overdue oil), then graph desired-versus-actual Bank 2 intake cam at idle and at 2,500 RPM — a working VVT actuator should hold within 1 to 2 degrees at idle and slew 30 to 50 degrees of authority cleanly when commanded.
- If the actual position drifts more than 3 degrees during a steady-state hold, swap the Bank 1 and Bank 2 intake OCVs (they are typically identical part numbers) and clear codes; if the fault follows the solenoid to Bank 1, you have a $50 to $90 part instead of a $1,200 phaser.
- The expensive misdiagnosis is condemning the variable cam actuator or timing chain set when the real culprit is a partially clogged OCV inlet screen.

- 2007-2011Toyota 2GR-FE (Camry V6, RAV4 V6, Sienna, Lexus RX350, ES350) sets P0025 from the dual VVT-i Bank 2 intake OCV failing.
- 2008-2014VW/Audi 3.2L VR6 and 3.0T V6 Audi platforms map P0025 to the rear-bank cam adjuster bolt backing out or the adjuster itself splitting internally.
- 2011-2016Hyundai/Kia 3.5L Lambda V6 (Santa Fe, Sorento, Azera) gets it from Bank 2 intake OCV sludge.

Is it safe to drive with a P0025 code?
Only if running normally. A short trip to a shop may be reasonable if the light is steady and the car runs normally. Stop safely for a flashing light, severe shaking, overheating, loss of power, or another urgent warning. The code alone cannot confirm safety. Estimated repair: $150-$800.
How do I diagnose a P0025 code?
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed. 1. Note every code that is set, not just this one. 2. Read the freeze frame — the conditions the fault was recorded under. 3. Confirm the fault is current rather than history. 4. Then work the likely-causes list in the order shown.
