This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has found a problem with the system that turns off some of the engine's cylinders to save fuel when they are not needed.
The code P3497 indicates an issue with the cylinder deactivation system on bank 2 of the engine. This system is designed to improve fuel efficiency by deactivating certain cylinders when full power is not needed.
Cylinder deactivation is a technology used in some engines to improve fuel efficiency by shutting down some of the engine's cylinders during light load conditions. Bank 2 refers to the side of the engine that contains cylinder number 2 in a V-type engine. The P3497 code is triggered when the Engine Control Module (ECM) detects that the deactivation system is not functioning properly on this bank.

Engine Performance
• Do not ignore the Check Engine Light.
• Get the vehicle checked by a professional mechanic.
Check with the vehicle manufacturer for warranty coverage on engine components.
Cylinder deactivation systems have been used in various vehicles to improve fuel efficiency, but issues can arise due to mechanical or electrical failures.
Moderate – While the vehicle can still be driven, it may experience reduced performance and increased fuel consumption.
Driving with a malfunctioning engine system can lead to increased emissions and may not comply with local environmental regulations.
• Engine at operating temperature
• Vehicle at idle and under load
The cylinder deactivation solenoid is located on the engine, typically near the cylinder head of bank 2.
Q: What does cylinder deactivation do?
A: It helps save fuel by turning off some cylinders when full engine power is not needed.
Q: Can I drive with a P3497 code?
A: Yes, but it is not recommended due to possible reduced performance and increased fuel consumption.
