Protect your engine with SensorGal’s Knock Sensors. These sensors detect abnormal combustion (engine knocking) and alert the ECU to adjust ignition timing, preventing damage and ensuring smooth performance.
A failing knock sensor can cause poor acceleration, increased fuel use, warning lights, or engine noise. Replacing it with an OEM-fit knock sensor restores performance and efficiency.
FAQs
Q: What does a knock sensor do?
A: It detects engine knock (pre-detonation) and signals the ECU to adjust timing.
Q: What are symptoms of a bad knock sensor?
A: Poor performance, check engine light, fuel inefficiency, or knocking noises.
Q: Why OEM-fit?
A: OEM-fit sensors ensure accurate detection and protect engine longevity.
