P3497 on Chevrolet
Cylinder Deactivation System Bank 2
P3497 on Chevrolet vehicles indicates cylinder deactivation system bank 2. Au7o has documented this code across 1 Chevrolet model — most commonly on Camaro. This code indicates the engine computer detected a fault in the fuel-saving cylinder deactivation system on bank 2 (the cylinder bank not containing cylinder #1). On engines with this feature, certain cylinders are shut down during light-load cruising to save fuel, controlled by oil-pressure-actuated solenoids and the valvetrain. The code sets when the system fails to switch those cylinders off or on as commanded, or sees an unexpected control circuit voltage. It often relates to oil level/pressure or a deactivation solenoid rather than a serious failure. Typical repair costs on Chevrolet range from $1,800 to $4,500, depending on the specific model and root cause.
Common Causes of P3497
- •Low engine oil level or low oil pressure
- •Faulty cylinder deactivation / VVT solenoid
- •Failed oil pressure switch/sensor
- •Clogged oil passages
- •Open or shorted deactivation control circuit
- •Wiring/connector fault to the solenoid
- •Internal valvetrain (lifter) mechanical fault
- •PCM fault

- L99 AFM Lifter Failure and Camshaft Damage on 6.2L Automatic Cars2010-2015
Automatic-transmission SS models with the 6.2L L99 V8 use Active Fuel Management lifters that are widely reported to collapse or stick, often leading to a misfire, valvetrain noise, and in many cases camshaft lobe damage. This problem is heavily documented across GM AFM-equipped V8 platforms and appears in Camaro owner complaints and forum repair threads. Repairs can become expensive because the cylinder heads and valvetrain must be opened, and many owners replace the cam and full lifter set once failure begins.
