Possible causes
- Sensor loose or torqued to the wrong value, so it transmits too little or distorted vibration
- Rust, paint, sealant or a washer between the sensor and its block mounting face
- Real, sustained knock from low-octane fuel, carbon deposits, overheating or a lean mixture
- Mechanical noise the computer mistakes for knock: loose heat shield, valvetrain clatter, timing chain slap
