Looking for a genuine knock control sensor that meets strict factory specifications and delivers reliable engine protection for your Toyota? The Genuine Toyota Sensor, Knock Control (Part No. 89615-12090) is manufactured to precise OEM standards and engineered to accurately detect engine knock and support optimized combustion performance you can depend on.

Critical Engine Management Component for Optimal Performance
The knock control sensor plays a vital role in your engine’s performance and durability. It continuously monitors vibrations caused by detonation (engine knock) and sends real-time feedback to the Engine Control Unit (ECU). This helps the ECU adjust ignition timing and fuel delivery to prevent damaging knock events, protect internal engine components, improve throttle response, support smoother acceleration, and maintain efficient combustion under varied driving conditions.

Factory-Quality Design & Durable Construction
Manufactured using premium materials and precision engineering, this OEM-spec sensor meets Toyota’s strict performance and durability standards. It integrates seamlessly with the original engine management system, responds accurately to combustion changes, resists environmental exposure and thermal stress, and delivers dependable long-term operation when installed and maintained according to recommended procedures.

Why Knock Control Sensor Replacement Matters
A faulty or degraded knock control sensor can lead to incorrect ignition timing, reduced power output, engine pinging or knocking, poor fuel economy, increased emissions, rough idle, and persistent ECU fault codes. Installing the correct Toyota knock control sensor restores proper feedback to the engine management system, enhances combustion stability, and helps protect your engine from avoidable damage.

Avoiding Incorrect or Aftermarket Substitutes
Using incompatible or low-quality aftermarket knock sensors may result in inaccurate readings, poor engine performance, increased risk of engine knock, drivability issues, and premature component wear. Choosing the genuine Toyota Sensor, Knock Control (89615-12090) ensures accurate fitment, reliable performance, and long-lasting durability you can trust.

Before purchasing, always verify the vehicle model, engine type, and OEM part number (89615-12090) to ensure correct compatibility and dependable operation.
