Overview

This sensor detects the audible knocking or pinging sound caused by premature ignition of the air-fuel mixture. Upon detection, it signals the engine computer to adjust engine timing and fuel delivery, thereby stopping the pre-detonation and protecting internal engine parts from damage. This Bosch sensor is a direct replacement for the original equipment.

When engine knock is detected for a sustained period, the engine computer may illuminate the check engine light with a fault code. This can be caused by excessive engine pressure due to carbon buildup, engine load, improper timing, or low-octane fuel. The knock sensor is mounted directly to the engine block to capture vibrations, though its location can make replacement challenging, potentially requiring removal of other components. Installation time can range from 20 minutes to four hours. Bosch is a leading global supplier of automotive components, ensuring OEM quality and specifications for their replacement parts.
