Knock Control Sensor

About this product

The Toyota Knock Control Sensor (#89615-WAA01), an essential electrical component in the Switch & Relay & Computer system, primarily detects engine knock or detonation. The sensor does this by monitoring vibrations in the engine and converting these into voltage signals for the engine control module. The module then adjusts the ignition timing to prevent further knocking. A worn-out knock control sensor can adversely affect the performance of your vehicle, leading to engine misfires, loss of power, and decreased fuel efficiency. Therefore, timely replacement with genuine Toyota parts is essential for compatibility and efficiency. These genuine Toyota parts come with the assurance of Toyota's genuine parts warranty. In essence, a functional knock control sensor helps maintain the engine's health, contributing to the overall performance and safety of your vehicle.
