Diagnostic trouble code P0306 on your 2022 Mazda CX-5 indicates a cylinder 6 misfire detection, creating an immediate diagnostic contradiction. The 2022 CX-5 uses four-cylinder engines exclusively, meaning there is no sixth cylinder to experience a misfire.
2022 CX-5 Powertrain Options
The 2022 Mazda CX-5 offers the Skyactiv-G 2.5-liter naturally aspirated four-cylinder producing 187 horsepower, and the Skyactiv-G 2.5 Turbo delivering 256 horsepower. Both are four-cylinder engines with only cylinders 1-4.
Code Investigation
Since the CX-5 lacks cylinder 6, P0306 represents diagnostic system malfunction. Possible causes include scanner errors, ECM software issues, or aftermarket device interference.
Diagnostic Steps
Verify with Mazda IDS diagnostics. Remove OBD-II accessories. If symptoms exist, diagnose cylinders 1-4.
