When your 2022 GMC Canyon displays diagnostic trouble code P0306, the engine control module has detected misfires in cylinder 6. The 2022 Canyon offered a V6 engine option, making P0306 a valid diagnostic code if equipped with six cylinders.
2022 Canyon Engine Options
The 2022 GMC Canyon (previous generation) offered the 3.6-liter V6 producing 308 horsepower as the primary engine. This V6 has six cylinders, making P0306 a legitimate code. The base 2.5L four-cylinder would show anomalous P0306.
V6 Cylinder 6 Location
On the 3.6L V6, cylinder 6 is positioned on the rear passenger-side bank. Access requires working around intake components. The coil-on-plug ignition system provides individual coils for each cylinder.
Common Causes
Ignition coil failure, spark plug wear, and fuel injector issues are typical. The 3.6L V6 can also experience carbon buildup on intake valves from direct injection.
