P0014 on Toyota by model: symptoms, diagnosis and fix
The 3.5L 2GR-FE V6 commonly develops oil leaks from the VVT-i oil line, timing cover, and valve cover gaskets. The rubber section of the VVT-i oil supply hose degrades over time and can leak (Toyota covered certain 2007-2010 Siennas under Limited Service Campaign 90K, now expired), dripping oil onto the exhaust manifold creating a burning smell and fire risk.
Common Symptoms
- Burning oil smell from engine bay
- Oil drips on driveway
- Oil on exhaust manifold
- Low oil level between changes
- Smoke from engine compartment
How to Fix
Tighten or replace VVT-i oil line and sealing washers (Toyota 15679-31010). Replace valve cover gaskets (Toyota 11213-31040 front, 11214-31030 rear). Timing cover reseal if leaking from that area. The VVT-i line fix is a $50 repair; valve cover gaskets run $300-600 due to rear cover access.

Frequently asked questions
What does P0014 mean on a Toyota?
P0014 stands for ""B" (Exhaust) Camshaft Position - Timing Over-Advanced or System Performance (Bank 1)." P0014 means the exhaust camshaft on bank 1 is timed too far advanced — the variable valve timing (VVT) system has moved the cam beyond the position the computer commanded, or it's stuck in an over-advanced position. The engine uses VVT to rotate the camshaft and optimize valve timing for power, economy, and emissions; the computer compares the commanded cam position to the actual reading from the cam sensor and flags this code when they don't agree. Common results are rough idle, reduced power, poor fuel economy, or a rattle at start-up. Oil flow and the VVT actuator are the usual suspects. On Toyota it is documented across 1 model: Sienna.
What are the most common causes of P0014?
The most common causes of P0014 are: Low or dirty engine oil restricting VVT operation, Stuck or failed camshaft oil control valve (VVT solenoid), Clogged VVT solenoid screen or oil passages, Faulty camshaft phaser/actuator, Wiring or connector fault at the oil control valve, Stretched timing chain or jumped timing, Camshaft position sensor fault giving incorrect reading. The specific cause varies by vehicle.
How much does it cost to fix P0014 on a Toyota?
Published repair estimates on Toyota range from $50 to $800 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
