The P0303 diagnostic trouble code on your 2024 Acura MDX indicates the powertrain control module has detected consistent misfires in cylinder 3. The 2024 MDX offers both V6 and turbocharged V6 powertrains.
2024 MDX Powertrain Options
The 2024 MDX uses the 3.5L V6 with VCM, while the Type S features a 3.0L turbocharged V6. Cylinder 3 is on the driver's side for both engines. The Type S turbo has different diagnostic considerations than the standard V6.
Typical Causes
- Ignition Coil Problems: Turbo Type S has higher ignition demands
- Spark Plug Condition: Turbo engines stress spark plugs more
- VCM System Issues: Standard V6's cylinder deactivation concerns
- Boost System Leaks: Type S turbo sensitive to intake leaks
- Fuel Injector Issues: Direct injection deposits or failures
Diagnostic Process
Identify your powertrain type first. Use Acura diagnostic equipment for detailed access. Monitor VCM on standard V6 or boost pressure on Type S. Test ignition components systematically.
Repair Recommendations
Replace faulty ignition coils with OEM components. Install engine-appropriate spark plugs. Address VCM-related issues on standard V6. Repair boost leaks on Type S. Professional carbon cleaning helps higher mileage vehicles.
