NOTE: Each tire pressure sensor is numbered and that number is assigned in the order as its ID code is registered in BCM. It does not indicate the tire position (front-left, front-right, rear-left and rear-right). Check what number of the tire pressure sensor is assigned to which tire, referring to How to Identify Tire Pressure Sensor Number.
