P0022 on Subaru
Intake Camshaft Position Timing - Over-Retarded (Bank 2)
P0022 on Subaru vehicles indicates intake camshaft position timing - over-retarded (bank 2). Au7o has documented this code across 1 Subaru model — most commonly on BRZ. 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 Subaru range from $50 to $500, 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

- FA20 Engine Oil Consumption During Spirited Driving2013-2021
The FA20 engine in the BRZ consumes oil at elevated rates during high-RPM driving, spirited canyon runs, and track use. The engine design with direct injection and high compression (12.5:1) combined with the oil-fed variable valve timing system means oil consumption increases significantly when the engine is frequently operated above 5,000 RPM. Consumption rates of 1 quart per 1,000-2,000 miles are reported by owners who drive aggressively. The narrow oil galleries in the FA20 make proper oil level maintenance critical.

What does P0022 mean on Subaru?▼
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 Subaru specifically, this code is documented across 1 model.
What causes P0022 on Subaru vehicles?▼
Common causes on Subaru: 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. Specific causes vary by model and year — see the per-model sections below.
