Mazda6 2005 OBD2 Code P0328: Knock Sensor Issue and Engine Not Starting
My 2005 Mazda6 is showing an OBD2 diagnostic code P0328, indicating a knock sensor fault. The vehicle is not starting at all. I'm looking for clear steps to diagnose and resolve this issue. Can someone please explain the correct troubleshooting process for this specific error code in a 2005 Mazda6?
Are there any other diagnostic trouble codes present? P0328 typically relates to knock sensor performance and is less likely to directly cause a no-start condition. If the engine cranks but does not start, try spraying starting fluid into the intake manifold or check for spark to rule out ignition system issues.
