A P0302 code on your 2022 Cadillac Escalade indicates that the engine control module has detected cylinder 2 misfires beyond acceptable parameters. This flagship luxury SUV features powerful engines requiring specific diagnostic attention.
2022 Escalade Engine Options
The 2022 Cadillac Escalade offered two engines: the 6.2L V8 producing 420 horsepower and the 3.0L Duramax turbo diesel delivering 277 horsepower with 460 lb-ft of torque. Each requires different diagnostic approaches.
6.2L V8 with DFM
The gasoline V8 features Dynamic Fuel Management (DFM) cylinder deactivation. This system can shut down cylinder 2 during light-load driving. DFM lifter issues have been documented and can cause cylinder-specific misfires.
3.0L Duramax Diesel
The turbo diesel uses compression ignition, eliminating spark-related causes. P0302 on the diesel indicates fuel injection, compression, or glow plug issues. Different diagnostic tools and approaches are required.
Flagship Luxury Standards
The Escalade is Cadillac's flagship, expected to provide supremely smooth, refined operation. Any misfire noticeably disrupts this luxury experience and should be addressed immediately.
DFM Lifter Concerns
GM's DFM system uses specialized lifters that can develop issues. Misfires specifically occurring during cylinder deactivation cycles may indicate lifter problems requiring repair or replacement.
