The P0306 diagnostic code on your 2024 Cadillac Escalade indicates a cylinder 6 misfire condition. The Escalade's powerful 6.2L V8 engine produces 420 horsepower (or 682 hp in the Escalade-V) and has 8 cylinders, making this a valid diagnostic code.
2024 Escalade Powertrains
- Standard Escalade: 6.2L V8 (420 hp) with DFM
- Escalade-V: 6.2L Supercharged V8 (682 hp)
Both variants have 8 cylinders, making P0306 valid for either.
Dynamic Fuel Management Considerations
The standard Escalade's Dynamic Fuel Management (DFM) system can deactivate up to half the cylinders. Issues with the cylinder 6 DFM lifter or solenoid can cause misfires, particularly during deactivation transitions. The supercharged Escalade-V does not use DFM.
Common Causes
- DFM Lifter Failure: Deactivation lifter malfunction
- Ignition Coil Issues: Coil-on-plug degradation
- Spark Plug Wear: Worn electrodes requiring replacement
- Fuel Injector Problems: Direct injection issues
- Supercharger Issues (V Model): Boost-related concerns
