P0022 on Mazda
Intake Camshaft Position Timing - Over-Retarded (Bank 2)
P0022 on Mazda vehicles indicates intake camshaft position timing - over-retarded (bank 2). Au7o has documented this code across 1 Mazda model — most commonly on Mazda6. 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 Mazda range from $400 to $1,200, 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
P0022 on Mazda by Model
Mazda Mazda6(1 issue)
- Variable Valve Timing (VVT) Actuator Failure2009-2021
The exhaust-side VVT actuator (cam phaser) fails due to oil sludge and wear, causing timing codes and engine rattle. The actuator solenoid can also stick, leading to incorrect valve timing. Oil change neglect accelerates failure. Common on both MZR and early SkyActiv 2.5L engines.

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