P0022 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 P0022 mean on a Toyota?
P0022 stands for "Intake Camshaft Position Timing - Over-Retarded (Bank 2)." This code means the engine computer found that the intake camshaft on bank 2 is timed too far retarded — more delayed than it commanded through the variable valve timing (VVT) system. The computer adjusts cam timing using an oil-controlled actuator (a phaser) and an electric solenoid, then verifies the cam actually moved to the target position. When the intake cam on bank 2 lags behind its commanded position, this code sets, often causing rough idle, reduced power, or lower fuel economy. (Bank 2 is the cylinder bank that does not contain cylinder 1.) It usually traces back to oil flow, the VVT solenoid, or the phaser. On Toyota it is documented across 1 model: Sienna.
What are the most common causes of P0022?
The most common causes of P0022 are: Low or dirty engine oil restricting VVT operation, Stuck or clogged camshaft (VVT) oil control solenoid, Clogged VVT oil passages or screen, Worn camshaft phaser/actuator on bank 2, Stretched or worn timing chain affecting cam timing, Electrical fault in the VVT solenoid wiring or connector, Incorrect oil viscosity or overdue oil change. The specific cause varies by vehicle.
How much does it cost to fix P0022 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.
