Standard Ignition Ignition Knock (Detonation) Sensor P/N:KS349
Keep your engine's spark timing in check with the Standard Ignition Ignition Knock (Detonation) Sensor KS483 — the chevy Malibu sensor that detects the tell-tale vibrations of detonation and reports them to the ECM. It drops in as a direct-fit replacement for the 2016-2019 Buick Cascada and 2016-2019 Chevrolet Malibu; see the Buyer's Guide tab for engine-specific coverage.
A knock sensor mounts to the engine block and converts the high-frequency vibrations of pre-ignition into a voltage signal, allowing the engine controller to retard timing when knock is present. If a failed sensor is the cause of a stored knock-related code, a rough-running condition, or reduced performance, this replaces it.

What vehicles does the KS483 knock sensor fit?
It is a direct-fit replacement for the 2016-2019 Buick Cascada and 2016-2019 Chevrolet Malibu. Check the Buyer's Guide tab to confirm the engine-specific application for your vehicle.
What does a knock sensor do?
It detects the high-frequency vibrations of engine knock (detonation) and sends a voltage signal to the engine controller, which can then retard ignition timing to help manage the condition.
Will this fix my Malibu sensor code?
If a failed knock sensor is the cause of a stored knock-related trouble code, this replaces it. Diagnose the cause first, since knock codes can have other sources.
What frequency range does the KS483 respond to?
It is designed to respond to knock frequencies of up to 1000 Hz, allowing it to correct engine knock across an array of vehicle conditions.
How is this sensor tested?
An automated data acquisition system monitors its output for the correct voltage at the specified frequency range, and every unit undergoes 100% accelerometer vibration testing.
