Not installing a knock sensor can lead to engine knocking or pinging, which can cause significant engine damage over time. The knock sensor detects abnormal vibrations and helps the engine control unit adjust ignition timing to prevent knocking. Without it, the engine may run inefficiently, experience reduced performance, and face a higher risk of costly repairs. Overall, omitting a knock sensor compromises engine health and longevity.
