DTC P1523: Throttle Rest Position: Description

WARNING: This page is about a different car, the 2002 Oldsmobile Bravada, 2002 GMC Envoy XL, 2002 GMC Envoy, and 2002 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.

During Battery Saver Mode, the Powertrain Control Module (PCM) determines if the throttle plate is returning to the correct de-energized position. If the PCM determines the throttle plate is not at the correct position during battery saver mode, this Diagnostic Trouble Code (DTC) is set.
