Abstract
Methods and apparatus are provided for determining the cause of tire pressure change. The method includes obtaining a first tire pressure (P1) at a first tire temperature (T1) and obtaining a measured second tire pressure (P2) at a second tire temperature (T2). The tire pressure is then estimated (Pest) at the second tire temperature (T2) and the estimated tire pressure (Pest) is compared to the second tire pressure (P2). A diagnostic message is then generated indicative of the cause of tire pressure change, the diagnostic message being responsive to the comparing of the measured second tire pressure (P2) with the estimated tire pressure (Pest).
