Introduction

Some Toyota vehicles may exhibit a rattle or buzz type noise coming from the driver’s instrument panel area. The noise can be duplicated when lightly accelerating and then decelerating, or when depressing the brake pedal with the shift lever in Park and then releasing brake pedal. An updated vacuum check valve is now available to reduce this noise.
