Standard Ignition KS342 sensor for the 2007-2008 Mazda 3 4-cylinder 2.0L, the 2007-2013 3 4-cylinder 2.3L and other vehicles detects engine knock and sends a voltage signal to the engine computer.
- Responds to knock frequencies up to 1000 Hz and follows shifts in engine knock frequency over a broad range of conditions
- 100% tested with an accelerometer-based vibration test
- Output monitored by an automated data acquisition system during manufacturing for correct voltage across the specified frequency range
