Keep a watchful ear on engine detonation with the Standard Ignition Knock (Detonation) Sensor KS483, a direct-fit Chevy Malibu knock sensor replacement for the 2016-2019 Chevrolet Malibu that also fits the 2016-2019 Buick Cascada. A knock sensor detects the vibration caused by engine knock, or detonation, and sends a signal to the engine control module, which can then adjust ignition timing. See the "Vehicles it fits" section for engine details on each application.
- Controlled quality: As a global manufacturer, Standard Ignition maintains complete quality control throughout the manufacturing process.
- Monitored output: An automated data acquisition system continuously checks sensor output to confirm it responds with the appropriate voltage at the specified frequency range.
- Knock response up to 1000 Hz: Designed to respond to knock frequencies of up to 1000 Hz, helping the engine control system correct knock across an array of vehicle conditions.
- Vibration tested: Every sensor undergoes 100% accelerometer vibration testing to verify durability and performance under harsh conditions.
Signs a knock sensor may need replacing include a check engine light with knock sensor codes, pinging or rattling under load, and sluggish performance or reduced fuel economy. These symptoms can have other causes, so diagnose the issue before replacing the sensor. If a failed knock sensor is the cause, the KS483 replaces it as a direct-fit replacement for the listed applications.
