When your 2022 Chevrolet Camaro displays the P0305 code, the engine control module has detected repeated misfires in cylinder 5. The 2022 Camaro continues with three engine options: the 2.0L turbo four-cylinder, 3.6L V6, and V8 variants (6.2L LT1 in SS, supercharged LT4 in ZL1). P0305 is valid only on V6 and V8 models.
Engine Configuration Check
Determine which engine your Camaro has before diagnosing. The 2.0L Turbo I-4 has only cylinders 1-4—P0305 would be anomalous. The 3.6L V6 (335 hp) has cylinders 1-6. The 6.2L LT1 V8 (455 hp) and LT4 V8 (650 hp) have cylinders 1-8. Only V6 and V8 have cylinder 5.
Cylinder 5 Location
On the V6, cylinder 5 is on the rear bank. On the V8, cylinder 5 is at the front of the driver side (left) bank, following GM's convention of odd cylinders on the driver side.
Common Causes
Spark plug wear is accelerated by high-RPM operation common in sports cars. Ignition coil failure can occur, especially under demanding conditions. On V8s, Dynamic Fuel Management (upgraded from AFM) lifter issues can cause specific cylinder misfires. Direct injection carbon buildup affects valve sealing over time.
Diagnostic Approach
Verify engine type. Inspect cylinder 5's spark plug for wear or fouling. Test the ignition coil. On V8 models, check for DFM-related codes. Review driving habits—track use or aggressive driving accelerates wear on ignition components.
