DTC P1589: Acceleration Sensor Learning Value [01/2019 - 11/2022]: Description

WARNING: This page is about a different car, the 2022 Toyota Corolla, 2021 Toyota Corolla, 2020 Toyota Corolla, and 2019 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.

The ECM stores this DTC if Deceleration Sensor Zero Point Calibration has not been performed or has failed after system components, such as the ECM, have been replaced.
