P0022 on Toyota
Intake Camshaft Position Timing - Over-Retarded (Bank 2)
P0022 on Toyota vehicles indicates intake camshaft position timing - over-retarded (bank 2). Au7o has documented this code across 1 Toyota model — most commonly on Sienna. 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. Typical repair costs on Toyota range from $50 to $800, depending on the specific model and root cause.
Common Causes of P0022
- •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

- 3.5L 2GR-FE Oil Leak from VVT-i System and Timing Cover2007-2020
The 3.5L 2GR-FE V6 commonly develops oil leaks from the VVT-i oil line, timing cover, and valve cover gaskets. The VVT-i oil hose fitting loosens over time, dripping oil onto the exhaust manifold creating a burning smell and fire risk.

What does P0022 mean on 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 specifically, this code is documented across 1 model.
What causes P0022 on Toyota vehicles?▼
Common causes on Toyota: 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.
