Knock sensors typically do not have a specific replacement interval, as they are designed to last the lifetime of the vehicle under normal operating conditions. However, they may need to be replaced if they fail or if the vehicle exhibits symptoms such as poor engine performance, knocking noises, or trouble codes related to engine timing. Regular maintenance checks can help identify potential issues before they become serious. If you experience any of these symptoms, it's advisable to have the sensor tested or replaced as needed.
