Will installing this sensor change engine performance or diagnostics?

When installed correctly, this sensor restores proper knock detection input to the engine control module so timing strategies operate as intended. It is not a performance part; rather, it helps the ECU make accurate adjustments to prevent knock and maintain expected drivability and emissions behavior.

• Re-establishes factory knock detection signal to ECU
• Supports correct ignition timing adjustments by the engine control system
• Helps avoid false knock codes when the sensor is the root cause
• Non‑tunable, OE‑style replacement — maintains factory settings
