Detailed Description

Standard Ignition S2918 is a replacement knock sensor harness for Toyota Sequoia and Toyota Tundra models across the listed year ranges. This harness is built to restore the electrical path between the detonation sensor and the engine management system, helping maintain accurate knock sensor signal transfer under normal operating conditions. The weatherproof sealed design adds protection at the connection points, while the female and male connector arrangement supports proper harness integration. If you are searching for a Toyota Sequoia knock sensor harness or a Toyota Tundra ignition knock sensor harness, S2918 is the direct-fit part number to reference.

This part cross-references CONB11403 and EC2818 for the same application.

What It Is Used For

• Broken, brittle, or heat-damaged knock sensor harness wiring
• Intermittent detonation sensor signal loss
• Connector corrosion at the engine harness interface
• Check engine light concerns tied to knock sensor circuit faults
• Restoring proper harness routing on Toyota Sequoia and Toyota Tundra models

Installation Notes and Tips

Verify connector shape, terminal style, and vehicle year before installation. Inspect the mating connectors for corrosion, bent terminals, or damaged locking tabs before connecting the new harness. Route the harness away from hot exhaust components and moving engine parts to preserve the sealed electrical connection. Confirm the harness follows the original path on the Toyota Sequoia or Toyota Tundra application to avoid strain on the wiring.

Quality Assurance

Standard Ignition supplies replacement electrical components for ignition and engine management service, and S2918 is built to match the listed fitment and connector requirements for the specified Toyota applications.
