- Also called: automatic transmission output shaft speed sensor
- Fits: 2006-2012 Toyota RAV4 and other vehicles

A failing sensor can show up as an unsteady speedometer, odd shifting or cruise control that drops out. A damaged wiring connector can also trigger these signs, so they alone do not prove the sensor is the problem. When original equipment fails, this sensor is designed to fix the inherent failure issues.
Fits
The vehicles this sensor fits include the 2009-2013 Toyota Highlander and the 2005-2007 Toyota Avalon, with one sensor needed per vehicle. It is a direct-fit OE replacement designed to support smooth transmission shifting and proper cruise control. If your car is not named here, open the "Vehicles it fits" section and check your exact model and engine.
