The 2024 Acura RDX continues with the 2.0-liter turbocharged 4-cylinder engine as its sole powertrain option. A P0305 diagnostic trouble code indicating cylinder 5 misfire presents a diagnostic puzzle since this luxury compact SUV only contains a four-cylinder engine.
The P0305 Code Contradiction
Standard OBD-II code P0305 indicates "Cylinder 5 Misfire Detected," but the RDX's K20C2 turbocharged engine has cylinders numbered only 1 through 4. This code appearing suggests a diagnostic system anomaly requiring investigation.
2024 RDX Engine Details
The turbocharged 2.0-liter produces 272 horsepower and 280 lb-ft of torque. This modern engine features VTEC and direct injection technology. The inline-4 configuration is calibrated exclusively for four-cylinder operation.
Investigating the Anomalous Code
Proper diagnosis requires Honda/Acura HDS diagnostics to analyze actual misfire counter data for each of the four physical cylinders. Software updates and communication errors should be investigated.
Warranty Coverage
As a 2024 model, software-related diagnostic issues should be addressed under Acura warranty.
