Detailed Description

Standard Ignition SC389 is a vehicle speed sensor built for the Toyota RAV4 speed signal circuit on 2001-2005 models. This sensor uses a bolt-mount installation style and a single connector layout, helping maintain the original electrical interface and mounting pattern. The SC389 is a practical OE-style replacement when the factory sensor is no longer reading vehicle speed correctly.

This part cross-references Standard Ignition SC389 for the same application.

Common Issues It Can Help Solve

  • Inaccurate or erratic speedometer readings
  • Transmission shift concerns related to vehicle speed input
  • Illuminated check engine light tied to speed sensor faults
  • Loss of speed signal to the engine or transmission control system
  • Intermittent drivability issues caused by a failing speed sensor

Installation Notes and Tips

Verify connector shape, terminal count, and bolt-mount location before installation. The SC389 does not include a wiring harness, mounting bracket, or hardware, so reuse the existing vehicle-side components as applicable. Confirm the sensor seats fully and the connector locks securely to help prevent signal interruptions.

Quality Assurance

Standard Ignition supplies electrical replacement parts for service applications, and the SC389 is built to match the original sensor style used on listed Toyota RAV4 models. Confirm fitment by year, make, and model before ordering.
