Detailed Description

Standard Ignition SC718 is a vehicle speed sensor used to monitor transmission output speed and send that signal to the vehicle control system. The sensor’s rectangular connector shape, plug-in connection type, and bolt-mount design support a straightforward replacement on the transmission. For Subaru B9 Tribeca, Subaru Legacy, and Subaru Outback models from 2006-2007, this part number SC718 provides the correct electrical interface and mounting style for the listed applications.

When a speed sensor begins to fail, the vehicle may lose accurate speed input needed by the transmission and related control modules. Using the correct replacement sensor helps restore the signal path required for normal drivability and system operation.

What This Part Helps Address

• Inaccurate or intermittent vehicle speed readings
• Transmission shifting concerns related to missing speed input
• Illuminated warning lights tied to speed sensor faults
• Harsh, delayed, or inconsistent shift behavior
• Loss of speed signal communication to control modules

Installation Notes and Tips

Install SC718 on the transmission using the existing bolt-mount location and verify the connector matches the vehicle harness before installation. Inspect the connector terminals and surrounding wiring for corrosion, bent pins, or damage that could affect the new sensor’s performance. Confirm the application against the vehicle’s year, make, and model before service.

Quality Assurance

Standard Ignition is a recognized aftermarket brand for electrical and engine management components. SC718 is built as a replacement vehicle speed sensor for the listed Subaru applications and is identified by the OE cross-reference 24030AA181.
