The P1415 code on your 2022 Chevrolet Camaro indicates a misfire has been detected during cylinder deactivation mode. This GM-specific code affects your Camaro's 6.2L V8 engine equipped with Active Fuel Management (AFM) or Dynamic Fuel Management (DFM), which deactivates cylinders during light load conditions to improve fuel economy.
Understanding P1415 on Camaro
GM's cylinder deactivation technology uses oil pressure-actuated lifter assemblies to disable intake and exhaust valves on specific cylinders during cruising conditions. Code P1415 sets when the PCM detects misfire events specifically during deactivated cylinder operation, indicating a problem with the deactivation system rather than general engine misfires.
Common Symptoms
- Check engine light on
- Rough running during highway cruising
- Engine vibration when AFM/DFM engages
- Reduced fuel economy
- Hesitation during light throttle operation
- Audible misfire or popping
- May set additional misfire codes P0300-P0308
Primary Causes
- Faulty AFM/DFM lifter on affected cylinder
- AFM solenoid failure
- Low oil pressure affecting lifter operation
- Oil viscosity issues affecting AFM system
- VLOM (Valve Lifter Oil Manifold) failure
- Worn AFM lifter guides
- Contaminated or degraded engine oil
Diagnostic Procedure for 2022 Camaro
Begin by identifying which cylinder is misfiring during AFM mode using freeze frame data. Check engine oil level and condition - AFM systems are sensitive to oil quality. Monitor AFM solenoid operation with a scan tool that can display lifter states. Test oil pressure to ensure adequate supply to AFM components. Some technicians temporarily disable AFM using a tuner to verify if misfire disappears during normal V8 operation, confirming AFM-related cause.
Repair Solutions
Ensure proper oil level and use only GM-approved dexos1 specification oil. Replace failed AFM lifters - this typically requires camshaft removal for access. Replace the VLOM assembly if solenoids are faulty. Some owners opt to install AFM/DFM delete kits that replace active lifters with standard lifters and disable the system via tuning. After repair, clear codes and verify smooth operation in both V8 and V4 modes.
