| The knock sensor creates a voltage signal based on the vibrations caused by detonation. The computer uses this signal to retard timing when spark knock occurs.
What makes NAPA Echlin Knock Sensors the best.
- NAPA Echlin knock sensors are designed to respond to knock frequencies up to 1000 Hz accommodating shifts in engine knock frequency making it a more flexible sensor responding to correct engine knock over a broad range of vehicle conditions.
- Manufacturing processes include an automated data acquisition system to continuously monitor the sensor output to ensure that it responds with appropriate voltage output at the specified frequency range.
- All units are 100% tested using an accelerometer vibration test to ensure trouble-free operation.
