Diagnostic trouble code P0306 on your 2022 Mazda CX-30 indicates a cylinder 6 misfire detection, creating an immediate diagnostic contradiction. The CX-30 is powered exclusively by four-cylinder engines, meaning there is no sixth cylinder to experience a misfire.
2022 CX-30 Engine Configuration
The 2022 Mazda CX-30 offers the Skyactiv-G 2.5-liter naturally aspirated four-cylinder producing 186 horsepower, and the Skyactiv-G 2.5 Turbo delivering 250 horsepower. Both engines have only four cylinders numbered 1-4.
Code Investigation
Since the CX-30 lacks cylinder 6, P0306 represents diagnostic system malfunction. Possible causes include scanner errors, ECM software issues, or aftermarket device interference.
Diagnostic Approach
Verify with Mazda IDS diagnostics. Remove OBD-II accessories. If symptoms exist, diagnose cylinders 1-4.
