Standard Ignition ALS659 Tire Pressure Monitoring System (TPMS) Sensor - Rear Right

Standard Ignition ALS659 TPMS Sensor for Toyota Sienna

The Standard Ignition ALS659 is a tire pressure monitoring system sensor for rear right wheel applications on select Toyota Sienna models. It is built with a wheel-mounted design, a rectangular connector, and a 23-inch harness to match the original sensor layout used on the vehicle.

For Toyota Sienna TPMS service, this sensor supports direct replacement of the rear right wheel sensor on 2004-2010 models. It is a practical choice when replacing a failed TPMS sensor that triggers warning lights or prevents accurate tire pressure reporting.
