P0306 Code: 2022 Acura RDX – What It Means & Cost to Fix

P0306 Code on 2022 Acura RDX: Diagnostic Investigation Required

If your OBD-II scanner displays a P0306 code on your 2022 Acura RDX, this code requires immediate diagnostic investigation because it references a cylinder that doesn't exist in your vehicle.

2022 Acura RDX Engine Configuration

The 2022 Acura RDX is exclusively powered by a 2.0L turbocharged 4-cylinder engine producing 272 horsepower. This is the only engine option available for the RDX. A 4-cylinder engine only has cylinders 1 through 4, making a P0306 (cylinder 6 misfire) code physically impossible.

Why You're Seeing This Code

  • Scanner Misconfiguration: The diagnostic tool may be set to the wrong vehicle
  • Communication Error: Data transmission issues between scanner and vehicle
  • Vehicle Confusion: Scanner may have identified the vehicle as an MDX (which has V6)
  • ECU Software Issue: Rare software glitch generating impossible codes

What to Do

If your RDX is experiencing actual misfire symptoms, the correct codes would be P0301-P0304 for cylinders 1-4. Verify scanner configuration and try a different diagnostic tool to confirm accurate code reading.
