Code P0606 Chrysler Description

This fault code is activated when the internal diagnostics of the Powertrain Control Module (PCM) detect a read or write error within the module itself. The PCM promptly illuminates the Malfunction Indicator Lamp (MIL) light when the diagnostic test runs and fails. Conversely, the PCM will turn off the MIL light immediately after the diagnostic test runs successfully and passes. This specific fault code is solely caused by an internal issue in the PCM and could potentially prevent the engine from starting.
